Version 1.9.6 (7 May 2003 or thereabouts)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Major changes in 1.9.6:
- Improved threading support for glibc >= 2.3.2 (SuSE 8.2,
RedHat 9, to name but two ...) It turned out that 1.9.5
had problems with threading support on glibc >= 2.3.2,
usually manifested by threaded programs deadlocking in system calls,
or running unbelievably slowly. Hopefully these are fixed now. 1.9.6
is the first valgrind which gives reasonable support for
glibc-2.3.2. Also fixed a 2.3.2 problem with pthread_atfork().
- Majorly expanded FAQ.txt. We've added workarounds for all
common problems for which a workaround is known.
Minor changes in 1.9.6:
- Fix identification of the main thread's stack. Incorrect
identification of it was causing some on-stack addresses to not get
identified as such. This only affected the usefulness of some error
messages; the correctness of the checks made is unchanged.
- Support for kernels >= 2.5.68.
- Dummy implementations of __libc_current_sigrtmin,
__libc_current_sigrtmax and __libc_allocate_rtsig, hopefully
good enough to keep alive programs which previously died for lack of
them.
- Fix bug in the VALGRIND_DISCARD_TRANSLATIONS client request.
- Fix bug in the DWARF2 debug line info loader, when instructions
following each other have source lines far from each other
(e.g. with inlined functions).
- Debug info reading: read symbols from both "symtab" and "dynsym"
sections, rather than merely from the one that comes last in the
file.
- New syscall support: prctl(), creat(), lookup_dcookie().
- When checking calls to accept(), recvfrom(), getsocketopt(),
don't complain if buffer values are NULL.
- Try and avoid assertion failures in
mash_LD_PRELOAD_and_LD_LIBRARY_PATH.
- Minor bug fixes in cg_annotate.
