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; ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70562&edit=1
