New Comment:
Does PHP only crash when the mongo extension is loaded? If so, please
report this at http://pecl.php.net/package/mongo,
as bugs in PECL
extensions aren't dealt with in this bug tracker.

Finally got a backtrace:
/Zend/Zend_execute_API.c:437
437 Z_DELREF_PP(zval_ptr);
There is a mention in another frame about requesting php shutdown. Then
higher, it says it will cleanup a closure. Sadly, no execute and
zbacktrace output was empty.

Description:
------------
PHP crash either as a httpd module or as cli with `zend_mm_heap
corrupted`.
Please see https://bugzilla.redhat.com/show_bug.cgi?id=694630
This was initially thought as a fedora packaging bug, but even a
compiled from
source php is producing the same error.
Test script:
---------------
Please see https://bugzilla.redhat.com/show_bug.cgi?id=694630
for a
simple script.
Actual result:
--------------
Tested is using a 2 different virtual machines both running Fedora 14
x64. One
with php from yum, the other compiled.
gdb reports no backtrace and says there is no stack.
Apache 2.2 crashes, running php-cli too.
relevant strace output:
array(0) {
}
}
</div>
</div>
</body>
</html>) = 1681
write(2, "zend_mm_heap corrupted\n", 23zend_mm_heap corrupted
) = 23
exit_group(1) = ?
Another one with sessions:
pwrite(3, "cart|a:1:{s:2:\"id\";C:7:\"MongoId\""..., 63, 0) = 63
close(3) = 0
close(4) = 0
write(2, "zend_mm_heap corrupted\n", 23zend_mm_heap corrupted
) = 23
exit_group(1)
It appears php is crashing at the end of the request just before
delivering the
content, when a database of some sort is used.
