ad3d3e8f20
Fix possibly uninitilized variable handling.
...
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.

2010-01-14 13:32:58 -08:00

Fix spelling in memusagestat.c
2009-11-06 09:32:06 -08:00
cc49a5a883
Restore locking in free_check.
...
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.
2009-11-01 07:27:00 -08:00
ee6f35389c
Fix typos in format strings of malloc_info.

Add local assert function to avoid problems with memory allocation in
...
the real one.
2009-08-31 04:55:10 -07:00
1877ea16ca
Fix obstack* on i?86
...
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.
2009-07-31 07:26:36 -07:00
bec466d922
Fix race in corruption check.
...
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.
2009-07-16 09:54:34 -07:00
bea0ac1d87
Use rel semantics of cas instead of acq semantics with full barrier before 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.
2009-07-16 07:24:50 -07:00

Fix possible race when freeing object in fast bin list.
2009-07-02 03:30:55 -07:00
