Description: ------------ When I run the test script php crashes. I have this issue with cli 5.3.10, 5.3.16, and the 5.4 snapshot from the 15th on windows(I can't find a newer snapshot for windows).

I think this might be a case of a pathological regular expression. I tried converting the grouping parentheses to non-grouping, and it seems to have helped the regular expression complete matching on later versions of PHP, although it still fails on some older versions. <?php $sql = "'" . str_repeat('a', 10*1024); $match = "/'(\'|\\{2}|[^'])*'/"; $sql = preg_replace($match, '', $sql); var_dump($sql);This version with non-grouping parentheses works on later versions of PHP: <?php $sql = "'" . str_repeat('a', 10*1024); $match = "/'(?:\'|\\{2}|[^'])*'/"; $sql = preg_replace($match, '', $sql); var_dump($sql);
