Description:
------------
A unit test for our application causes a segfault in a certain block of code.  I recompiled PHP 5.1.4. with debugging symbols and it reports a number of memory leaks.  On all systems I've tried it on it either segfaults or produces a bus error.

Reproduce code:
---------------
This is happening deep inside one of the most complex parts of a pretty big application (95,000 lines of PHP not even counting any HTML templates and over 100 classes) and unfortunately I cannot see any way to produce any sort of test case that does not include the entire application.

Actual result:
--------------

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.
