Bug description: preg_match fails with Segmentation Fault on capturing
subpattern
Description:
------------
When running a preg_match with a capturing subpattern against large input,
php crashes with a Segmentation Fault
I tested this on OS X and OpenSuSE, same result
OS X:~$ php -v
PHP 5.2.6 (cli) (built: Jul 15 2008 12:18:21)
OpenSuSE:~# php -v
PHP 4.4.7 (cgi) (built: May 12 2008 10:19:51)
Reproduce code:
---------------
<?php
preg_match("/http:\/\/(.)+\.ru/i", str_repeat("http://google.ru";, 2000));
?>
Expected result:
----------------
PHP should handle the error or something other than letting PCRE crash php
Actual result:
--------------
jjohnston:~$ php -r 'preg_match("/http:\/\/(.)+\.ru/i",
str_repeat("http://google.ru";, 2000));'
Segmentation fault
