Description:
------------
This an extended version of the code I've sent for bug #48408 that also
crashes both PHP 5.2.9 and the latest snapshot of PHP 5.2 (with
different debug backtrace).
The same script crashes also the latest PHP 5.3-dev snapshot but
generates a different backtrace. The information about the environment:
- The script was run from PHP Command-Line Interface
- No extra patches or modifications were used (pure snapshot)
- No debugging symbols were used.
- Operating system: Arch Linux x86_64.
The problem may be related to http://bugs.php.net/bug.php?id=48408 as
the reproduce code is similar.
Reproduce code:
---------------
See:
http://media.zyxist.com/snippets/exception_segfault1.phps
Expected result:
----------------
"Exception thrown"
Actual result:
--------------
Core was generated by `/usr/local/php/bin/php
exception_segfault1.php'.
Program terminated with signal 11, Segmentation fault.
