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.
