2010-04-14Optimie x86-64 SSE4 memcmp for unaligned data.H.J. Lu
2010-04-08Fix possibly uninitilized variable handling.Ulrich Drepper
If malloc errors are ignored (which say aren't by default and never should be) malloc in the old, slow form might use an uninitialized variable.

2010-02-24Fix assertion in palloc and pvalloc as well.Petr Baudis
2010-02-10Undo unintended maloc change.Ulrich Drepper
2010-02-09Avoid PLT call to fegetenv on s390Andreas Schwab
2010-01-14Fix malloc_info without prioor allocations.Ulrich Drepper
2009-11-06Fix spelling in memusagestat.cHolger Hans Peter Freyther
2009-11-01Restore locking in free_check.Ulrich Drepper
This code is only used when MALLOC_CHECK_ is used. Then some bogus crashes and/or assert could result from the locking changes. The code ain't fast.
2009-10-29Fix typos in format strings of malloc_info.John Sullivan
2009-10-29Fix repairing of memusage trace files.Ulrich Drepper
2009-10-29Fix wrap-around in memusage.Andreas Schwab
2009-08-31Add local assert function to avoid problems with memory allocation inUlrich Drepper
the real one.
2009-07-31Fix obstack* on i?86Jakub Jelinek
obstack calls several callbacks, so on i?86 it'd better be compiled without -mpreferred-stack-boundary=2, otherwise the callbacks are called with misaligned stack.
2009-07-16Fix race in corruption check.Ulrich Drepper
With atomic fastbins the checks performed can race with concurrent modifications of the arena. If we detect a problem re-do the test after getting the lock.
2009-07-16Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek
it in _int_free The following patch fixes catomic_compare_and_exchange_*_rel definitions (which were never used and weren't correct) and uses catomic_compare_and_exchange_val_rel in _int_free. Comparing to the pre-2009-07-02 --enable-experimental-malloc state the generated code should be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use lwsync instead of isync barrier.
2009-07-02Fix possible race when freeing object in fast bin list.Ulrich Drepper
2009-06-18Add some more tests to malloc to detect corruptions.Ulrich Drepper
