Summary: Some combination of subject and pattern results in
"Segmentation fault"
Status: Bogus
Type: Bug
Package: PCRE related
Operating System: Linux 2.6.26-2 x86_64
PHP Version: 5.3.6
Block user comment: N
Private report: N
New Comment:
Sure it's a PCRE problem due to the fact it shouldn't crash PHP. So if libpcre
can't handle with it, php has to catch the error before calling the library
function.

This is a known issue from PCRE library, not a PHP issue.

Description:
------------
Using a special combination of subject and pattern results in a segmention
fault
error (or web server not sending any data to client). The problem was first
caused in a Zend framework environment (Zend_Filter_StripTags, line 298) but as
far as I isolated the responsible code, it crashes even php.
Test script:
---------------
$pattern = '~(</?)(\w*)((/(?!>)|[^/>])*)(/?>)~';
$subject = '
