Public bug reported:
The following file causes a segmentation fault:
<?php
throw new Exception(str_repeat('a', 916));
whereas the same statement with 915 characters shows the exception and
terminates gracefully.
The number of characters variies; in one of my applications, it chrashes
at 887 characters. Stack level does not seem to influence it.
If the exception is caught, the segfault does not occur.
Apache error log:
> [Sun Sep 01 16:16:04 2013] [error] [client 127.0.0.1] PHP Fatal error:

(ellipsis by me)
In /etc/apache2, there is no coredump. If you know a way to force the
coredump, please let me know.
