Bug description: preg_split cause Segmentation Fault
Description:
------------
This code cause segmentation fault in PHP Version 5.2.6-2ubuntu4.1
I can't check it on 5.2.9 for now. Please check.
If I reduce 200 (in for cycle) to 100, everything works.
If I delete ",'1'" at the end of $t string, everything works.
Reproduce code:
---------------
<?
$t = "'1','8','10','1','5','3','0','0','0','4','2','9','0','1';";
$a = "";
for ($i=0; $i<200; $i++)
$a .= $t;
print
preg_split("/;+(?=([^'|^\\\']*['|\\\'][^'|^\\\']*['|\\\'])*[^'|^\\\']*[^'|^\\\']$)/",
$a);
?>
Expected result:
----------------
Array
Actual result:
--------------
Segmentation Fault in error_log and empty page in browser.
