New Comment:
After updating all the extensions i still get the same thing.
I extra detail i can provide is that i occasionally get
zend_mm_heap corrupted
instead of segmentation fault
and the line where the segfault occurs is the condition line from:
#if ZEND_MM_SAFE_UNLINKING
if (UNEXPECTED(prev->next_free_block != mm_block) ||
UNEXPECTED(next->prev_free_block != mm_block)) {
zend_mm_panic("zend_mm_heap corrupted");
}
#endif

Hello,
I have compiled PHP 5.3.16(http://kr.php.net/get/php-5.3.16.tar.bz2) and i am
experiencing similar issues.
The new back-trace is:
[Thread debugging using libthread_db enabled]
Program received signal SIGSEGV, Segmentation fault.

I am still using some on the old php5.3.2 extensions but i am upgrading the one
by one - just in case i catch the culprit.
Please let me know if i can provide additional details.
Thanks.

There is no changelog entry for it. Your report is not specific enough, but we
need to know if it is happening in a current version before we bother spending
any time looking for it. chasing fixed bugs isn't the best use of our time.

Can you please point me to the change-log note for this fix?
I want to be 100% sure that it's the same issue, as we are trying to be as
conservative as possible with environment updates.
Thanks!

Ah, I see the version at the bottom of your report now. I have fixed it in the
report. 5.3.2 is from March 2010. Please upgrade to something more recent.

The PHP version is not irrelevant at all. We can't possibly do anything with
this
bug unless you tell us which version you are seeing it in.
