Hi Dennis, Thanks for trying it out, not seen that before. What toolchain are you using to compile? CodeSourcery? Can you send me a simple binary + libc to look at?

Johan, Thanks for posting the patch. I was able to compile but I'm having problems running valgrind. We're running uClibc 0.9.29 on ARMv9. I've read through some of the posts on valgrind with uclibc, but it's not clear to me if that is the problem. Here's the output of running ls under valgrind with memcheck. # valgrind -v ls ==164== Memcheck, a memory error detector. ==164== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al. ==164== Using LibVEX rev 71311, a library for dynamic binary translation. ==164== Copyright (C) 2004-2009, and GNU GPL'd, by OpenWorks LLP. ==164== Using valgrind-3.5.0.SVN, a dynamic binary instrumentation framework. ==164== Copyright (C) 2000-2009, and GNU GPL'd, by Julian Seward et al. ==164== --164-- Command line --164-- ls --164-- Startup, with flags: --164-- -v --164-- Contents of /proc/version: --164-- Linux version 2.6.28-leapfrog (rdowling@rdowling-laptop) (gcc version 4.1.1) #126 Tue Feb 24 08:55:41 PST 2009 --164-- Arch and hwcaps: ARM, arm-baseline --164-- Page sizes: currently 4096, max supported 4096 --164-- Valgrind library directory: /usr//lib/valgrind --164-- Reading syms from /bin/busybox (0x8000) --164-- object doesn't have a symbol table --164-- Reading syms from /lib/ld-uClibc-0.9.29.so (0x4000000) --164-- WARNING: Serious error when reading debug info --164-- When reading debug info from arm_commpage: --164-- failed to stat64/stat this file --164-- Reading suppressions file: /usr//lib/valgrind/default.supp ==164== Conditional jump or move depends on uninitialised value(s) ==164== at 0x4004C3C: _dl_get_ready_to_run (in /lib/ld-uClibc-0.9.29.so) ==164== by 0x4005BF7: ???

It contains workarounds to several common problems. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what Linux distro you are using. Thanks. # The fact that it can't read the symbols from busybox is worrisome. I get the same sort of error when running a program I compile myself, so busybox (v1.5.0) is probably not to blame. And always "object doesn't have a symbol table". I think I'm missing something very basic here. Let me know if there's info I can provide to be more helpful. thanks, Dennis |
