Referring to the source code, a string length greater than 376 character crashes the request. Rolling back to PHP 5.1.2, using PCRE 6.2 works correctly without crashing for string lengths greater than 376 characters. The bug is very similar to the following PHP bug report: http://bugs.php.net/bug.php?id=24460 Reproduce code: --------------- <?PHP $test = str_repeat('a',377); // preg_match() will crash the request preg_match('/(\r|\n|.)*/',$test); ?> Expected result: ---------------- The script to end gracefully. Actual result: -------------- Crashing of the PHP request. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38512&edit=1
