* Avoid potential deadlock in mtraceUlrich Drepper2011-05-161-23/+41
| | | | | The _dl_addr function might have to call malloc which would lead to a deadlock. Avoid by calling _dl_addr early.
* Remove USE_MTRACE_FILE support from mtraceUlrich Drepper2011-05-161-17/+2

|
* Fix possibly uninitilized variable handling.Ulrich Drepper2010-04-081-0/+1
| | | | | | 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.

|
* Restore locking in free_check.Ulrich Drepper2009-11-011-17/+20
| | | | | | 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.

| | | | the real one.
* Fix obstack* on i?86Jakub Jelinek2009-07-311-0/+1
| | | | | | 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.
* Fix race in corruption check.Ulrich Drepper2009-07-161-2/+23
| | | | | | 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.
* Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek2009-07-161-2/+1
| | | | | | | | | | | 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.
