Description:
------------
PHP Version: PHP 5.4.11-1~dotdeb.0 (cli) (built: Jan 24 2013 15:04:58) 

match causes a segfault when processing large strings.  Increasing the stack size 
from the default of 8192 to 16384 allows me to circumvent the problem.

dpkg -l 'php*' | grep '^.i':

-Status: Open +Status: Not a bug

[2013-02-01 14:10 UTC] pajoye@php.net

Yes, that's a well known "problem" in pcre. Not much we can do fix it and your 
workaround is actually the right solution.

[2016-03-25 09:55 UTC] martin at sutunam dot com

This "well-know" error is still a bug. It is also undocumented and should be wrapped by a check to throw a php error (and not a segfault in the system).

[2016-03-25 11:03 UTC] yohgaki@php.net

PHP does not detect if system's stack limit is reached or not.
One may request the detection if there is no request for it.
