Bug Description
The following file causes a segmentation fault:
<?php
throw new Exception(
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: Uncaught exception 'Exception' with message 'aa...aaaa' in /.../test.php:3 in /.../test.php on line 3
> [Sun Sep 01 16:16:04 2013] [notice] child pid 12198 exit signal Segmentation fault (11), possible coredump in /etc/apache2
(ellipsis by me)
In /etc/apache2, there is no coredump. If you know a way to force the coredump, please let me know.

I just noticed that only the first line of the exception message is affected.
throw new Exception(
performs well. Notice that the length of the first line may be longer if there are multiple lines (978 vs. 916). However, adding more lines does not further increase the length.
*mind blown*
