Background -2. Compiling, installing and configuring -3. Valgrind aborts unexpectedly -4. Valgrind behaves unexpectedly -5. Memcheck doesn't find my bug -6. Miscellaneous - - ------------------------------------------------------------------ -1. Background ------------------------------------------------------------------ - -1.1. How do you pronounce "Valgrind"? - -The "Val" as in the world "value". The "grind" is pronounced with a -short 'i' -- ie. "grinned" (rhymes with "tinned") rather than "grined" -(rhymes with "find"). - -Don't feel bad: almost everyone gets it wrong at first. - ------------------------------------------------------------------ - -1.2. Where does the name "Valgrind" come from? - -From Nordic mythology. Originally (before release) the project was -named Heimdall, after the watchman of the Nordic gods. He could "see a -hundred miles by day or night, hear the grass growing, see the wool -growing on a sheep's back" (etc). This would have been a great name, -but it was already taken by a security package "Heimdal". - -Keeping with the Nordic theme, Valgrind was chosen. Valgrind is the -name of the main entrance to Valhalla (the Hall of the Chosen Slain in -Asgard). Over this entrance there resides a wolf and over it there is -the head of a boar and on it perches a huge eagle, whose eyes can see to -the far regions of the nine worlds. Only those judged worthy by the -guardians are allowed to pass through Valgrind. All others are refused -entrance. - -It's not short for "value grinder", although that's not a bad guess. - - ------------------------------------------------------------------ -2. Compiling, installing and configuring ------------------------------------------------------------------ - -2.1. When I trying building Valgrind, 'make' dies partway with an - assertion failure, something like this: make: expand.c:489: - =20 - allocated_variable_append: Assertion=20 - `current_variable_set_list->next !=3D 0' failed. - =20 -It's probably a bug in 'make'. Some, but not all, instances of version = 3.79.1 -have this bug, see www.mail-archive.com/bug...@gn.../msg01658.html. = Try -upgrading to a more recent version of 'make'. Alternatively, we have he= ard -that unsetting the CFLAGS environment variable avoids the problem. - - ------------------------------------------------------------------ -3. Valgrind aborts unexpectedly ------------------------------------------------------------------ - -3.1. Programs run OK on Valgrind, but at exit produce a bunch of errors = a bit - like this - - =3D=3D20755=3D=3D Invalid read of size 4 - =3D=3D20755=3D=3D at 0x40281C8A: _nl_unload_locale (loadlocale.c:= 238) - =3D=3D20755=3D=3D by 0x4028179D: free_mem (findlocale.c:257) - =3D=3D20755=3D=3D by 0x402E0962: __libc_freeres (set-freeres.c:34= ) - =3D=3D20755=3D=3D by 0x40048DCC: vgPlain___libc_freeres_wrapper=20 - (vg_clientfuncs.c:585) - =3D=3D20755=3D=3D Address 0x40CC304C is 8 bytes inside a block of= size 380 free'd - =3D=3D20755=3D=3D at 0x400484C9: free (vg_clientfuncs.c:180) - =3D=3D20755=3D=3D by 0x40281CBA: _nl_unload_locale (loadlocale.c:= 246) - =3D=3D20755=3D=3D by 0x40281218: free_mem (setlocale.c:461) - =3D=3D20755=3D=3D by 0x402E0962: __libc_freeres (set-freeres.c:34= ) - - and then die with a segmentation fault. - -When the program exits, Valgrind runs the procedure __libc_freeres() in -glibc. This is a hook for memory debuggers, so they can ask glibc to -free up any memory it has used. Doing that is needed to ensure that -Valgrind doesn't incorrectly report space leaks in glibc. - -Problem is that running __libc_freeres() in older glibc versions causes -this crash. =20 - -WORKAROUND FOR 1.1.X and later versions of Valgrind: use the ---run-libc-freeres=3Dno flag. You may then get space leak reports for -glibc-allocations (please _don't_ report these to the glibc people, -since they are not real leaks), but at least the program runs. - ------------------------------------------------------------------ - -3.2. My (buggy) program dies like this: - valgrind: vg_malloc2.c:442 (bszW_to_pszW):=20 - Assertion `pszW >=3D 0' failed. - -If Memcheck (the memory checker) shows any invalid reads, invalid writes -and invalid frees in your program, the above may happen. Reason is that -your program may trash Valgrind's low-level memory manager, which then -dies with the above assertion, or something like this. The cure is to -fix your program so that it doesn't do any illegal memory accesses. The -above failure will hopefully go away after that. - ------------------------------------------------------------------ - -3.3. My program dies, printing a message like this along the way:=20 - - disInstr: unhandled instruction bytes: 0x66 0xF 0x2E 0x5 - -Older versions did not support some x86 instructions, particularly -SSE/SSE2 instructions. Try a newer Valgrind; we now support almost all -instructions. If it still happens with newer versions, if the failing -instruction is an SSE/SSE2 instruction, you might be able to recompile -your program without it by using the flag -march to gcc. Either way, -let us know and we'll try to fix it. - -Another possibility is that your program has a bug and erroneously jumps -to a non-code address, in which case you'll get a SIGILL signal. -Memcheck/Addrcheck may issue a warning just before this happens, but the= y -might not if the jump happens to land in addressable memory. - - ------------------------------------------------------------------ -4. Valgrind behaves unexpectedly ------------------------------------------------------------------ - -4.1. My threaded server process runs unbelievably slowly on Valgrind. - So slowly, in fact, that at first I thought it had completely - locked up. - -We are not completely sure about this, but one possibility is that -laptops with power management fool Valgrind's timekeeping mechanism, -which is (somewhat in error) based on the x86 RDTSC instruction. A -"fix" which is claimed to work is to run some other cpu-intensive -process at the same time, so that the laptop's power-management -clock-slowing does not kick in. We would be interested in hearing more -feedback on this. - -Another possible cause is that versions prior to 1.9.6 did not support -threading on glibc 2.3.X systems well. Hopefully the situation is much -improved with 1.9.6 and later versions. - ------------------------------------------------------------------ - -4.2. My program uses the C++ STL and string classes. Valgrind - reports 'still reachable' memory leaks involving these classes - at the exit of the program, but there should be none. - -First of all: relax, it's probably not a bug, but a feature. Many -implementations of the C++ standard libraries use their own memory pool -allocators. Memory for quite a number of destructed objects is not -immediately freed and given back to the OS, but kept in the pool(s) for -later re-use. The fact that the pools are not freed at the exit() of -the program cause Valgrind to report this memory as still reachable. -The behaviour not to free pools at the exit() could be called a bug of -the library though. - -Using gcc, you can force the STL to use malloc and to free memory as -soon as possible by globally disabling memory caching. Beware! Doing -so will probably slow down your program, sometimes drastically. - -- With gcc 2.91, 2.95, 3.0 and 3.1, compile all source using the STL - with -D__USE_MALLOC. Beware! This is removed from gcc starting with - version 3.3. - -- With gcc 3.2.2 and later, you should export the environment variable - GLIBCPP_FORCE_NEW before running your program. - -- With gcc 3.4 and later, that variable has changed name to - GLIBCXX_FORCE_NEW. - -There are other ways to disable memory pooling: using the malloc_alloc -template with your objects (not portable, but should work for gcc) or -even writing your own memory allocators. But all this goes beyond the -scope of this FAQ. Start by reading -http://gcc.gnu.org/onlinedocs/libstdc++/ext/howto.html#3 if you -absolutely want to do that. But beware: - -1) there are currently changes underway for gcc which are not totally - reflected in the docs right now ("now" =3D=3D 26 Apr 03) - -2) allocators belong to the more messy parts of the STL and people went - at great lengths to make it portable across platforms. Chances are - good that your solution will work on your platform, but not on - others. - -------------------------------------------------------------------------= ----- -4.3. The stack traces given by Memcheck (or another tool) aren't helpful= . - How can I improve them? - -If they're not long enough, use --num-callers to make them longer. - -If they're not detailed enough, make sure you are compiling with -g to a= dd -debug information. And don't strip symbol tables (programs should be -unstripped unless you run 'strip' on them; some libraries ship stripped= ). - -Also, for leak reports involving shared objects, if the shared object is -unloaded before the program terminates, Valgrind will discard the debug -information and the error message will be full of "???" entries. The -workaround here is to avoid calling dlclose() on these shared objects. - -Also, -fomit-frame-pointer and -fstack-check can make stack traces worse= . - -Some example sub-traces: - - With debug information and unstripped (best): - - Invalid write of size 1 - at 0x80483BF: really (malloc1.c:20) - by 0x8048370: main (malloc1.c:9) - - With no debug information, unstripped: - - Invalid write of size 1 - at 0x80483BF: really (in /auto/homes/njn25/grind/head5/a.out) - by 0x8048370: main (in /auto/homes/njn25/grind/head5/a.out) - - With no debug information, stripped: - - Invalid write of size 1 - at 0x80483BF: (within /auto/homes/njn25/grind/head5/a.out) - by 0x8048370: (within /auto/homes/njn25/grind/head5/a.out) - by 0x42015703: __libc_start_main (in /lib/tls/libc-2.3.2.so) - by 0x80482CC: (within /auto/homes/njn25/grind/head5/a.out) - - With debug information and -fomit-frame-pointer: - - Invalid write of size 1 - at 0x80483C4: really (malloc1.c:20) - by 0x42015703: __libc_start_main (in /lib/tls/libc-2.3.2.so) - by 0x80482CC: ??? (start.S:81) - - A leak error message involving an unloaded shared object: - - 84 bytes in 1 blocks are possibly lost in loss record 488 of 713 - at 0x1B9036DA: operator new(unsigned) (vg_replace_malloc.c:132) - by 0x1DB63EEB: ??? - by 0x1DB4B800: ??? - by 0x1D65E007: ??? - by 0x8049EE6: main (main.cpp:24) - -------------------------------------------------------------------------= ----- -4.4. The stack traces given by Memcheck (or another tool) seem to - have the wrong function name in them. What's happening? - -Occasionally Valgrind stack traces get the wrong function names. -This is caused by glibc using aliases to effectively give one function -two names. Most of the time Valgrind chooses a suitable name, but -very occasionally it gets it wrong. - -Examples we know of are printing 'bcmp' instead of 'memcmp', 'index' -instead of 'strchr', and 'rindex' instead of 'strrchr'. - ------------------------------------------------------------------ -5. Memcheck doesn't find my bug ------------------------------------------------------------------ - -5.1. I try running "valgrind --tool=3Dmemcheck my_program" and get - Valgrind's startup message, but I don't get any errors and I know - my program has errors. - -There are two possible causes of this. - =20 -First, by default, Valgrind only traces the top-level process. So if yo= ur -program spawns children, they won't be traced by Valgrind by default. -Also, if your program is started by a shell script, Perl script, or -something similar, Valgrind will trace the shell, or the Perl -interpreter, or equivalent. - -To trace child processes, use the --trace-children=3Dyes option. - -If you are tracing large trees of processes, it can be less disruptive -to have the output sent over the network. Give Valgrind the flag ---log-socket=3D127.0.0.1:12345 (if you want logging output sent to port -12345 on localhost). You can use the valgrind-listener program to -listen on that port: - - valgrind-listener 12345=20 - =20 -Obviously you have to start the listener process first. See the -documentation for more details. - -Second, if your program is statically linked, most Valgrind tools won't -work as well, because they won't be able to replace certain functions, -such as malloc(), with their own versions. A key indicator of this is -if Memcheck says: - - No malloc'd blocks -- no leaks are possible - -when you know your program calls malloc(). The workaround is to avoid -statically linking your program. - ------------------------------------------------------------------ - -5.2. Why doesn't Memcheck find the array overruns in this program? - - int static[5]; - - int main(void) - { - int stack[5]; - - static[5] =3D 0; - stack [5] =3D 0; - =20 - return 0; - } - -Unfortunately, Memcheck doesn't do bounds checking on static or stack -arrays. We'd like to, but it's just not possible to do in a reasonable -way that fits with how Memcheck works. Sorry. - - ------------------------------------------------------------------ -6. Miscellaneous ------------------------------------------------------------------ - -6.1. I tried writing a suppression but it didn't work. Can you=20 - write my suppression for me? - -Yes! Use the --gen-suppressions=3Dyes feature to spit out suppressions -automatically for you. You can then edit them if you like, eg. -combining similar automatically generated suppressions using wildcards -like '*'. - -If you really want to write suppressions by hand, read the manual -carefully. Note particularly that C++ function names must be _mangled_. - ------------------------------------------------------------------ - -6.2. With Memcheck/Addrcheck's memory leak detector, what's the - difference between "definitely lost", "possibly lost", "still - reachable", and "suppressed"? - -The details are in section 3.6 of the manual. - -In short: - - - "definitely lost" means your program is leaking memory -- fix it! - - - "possibly lost" means your program is probably leaking memory, - unless you're doing funny things with pointers. - - - "still reachable" means your program is probably ok -- it didn't - free some memory it could have. This is quite common and often - reasonable. Don't use --show-reachable=3Dyes if you don't want to s= ee - these reports. - - - "suppressed" means that a leak error has been suppressed. There are - some suppressions in the default suppression files. You can ignore - suppressed errors. - ------------------------------------------------------------------ - -(this is the end of the FAQ.)
