Setting apc.enable_cli=0 so far has eliminated the issue.
I don't this fixed the underlying issue but at least it gets rid of the nasty
exit code at the end on the script.

if I don't get a script to reproduce it, then I think,, I can do nothing..
since
there is not much info can get from the backtrace

I could, but i think it won't help much. As i stated initially it's a cli
script form a Magento/ZF application with quite a few contributed modules.
If i can get to a one file script that produces the error i will post it.
Is there anything else you can do while you don't have that?

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.
