Description:
------------
Running preg_replace on a string length over 8435 causes a segmentation fault. Running default
php.ini config.
Please see attached script to reproduce. This happens on the CLI as well as through an apache
handler.
Test script:
---------------
<?php
$pattern = '/(.)*/';
$limit = 9000;
$string = 'a';
for ( $i = 0; $i <= $limit; $i++ ) {
$string .= 'a';
echo strlen($string) . "\n";
echo mb_strlen($string);
preg_replace($pattern, '', $string);
}
echo 'done';
exit;
