New Comment:
Sorry but I can't understand what's going on, while I can't reproduce
it myself. The best case if you can provide a script which crashes PHP
running from command line (it may be a big code base but without
dependencies on external resources like databases and etc)

Description:
------------
We got a huge framework which runs as CLI.
With lots of circular references, we use 5.3 as it
solves the out of memory problem.
Unfortunately it crashes randomly after a while.
We can't reproduce it as it crashes, as it likes.
Reproduce code:
---------------
Not possible, as we can't locate a specific line of code.
Happens randomly
Actual result:
--------------
The GDP output for this problem:
Core was generated by `/blade/exec/10.1.0.10/php/bin/php
-c/blade/run/configs/10.1.0.10-php-daemon.ini'.
