Description

I cant update the extension-list, everytime this error occurs:

Error in regular expression matching, code: PREG_BACKTRACK_LIMIT_ERROR
See http://www.php.net/manual/en/function.preg-last-error.php

After change the limit in /typo3/sysext/em/classes/tools/class.tx_em_tools_xmlhandler.php from 500.000 to 1.000.000 the update went fine

I can confirm this issue in a TYPO3 CMS 4.5.40 instance.
Increasing ini_set('pcre.backtrack_limit', 500000); in line 418 to 1000000 fixed it for me, too.

As TYPO3 CMS 4.5 is in "security only" bugfix mode, this is considered closed.

Please consider upgrading to a recent version (6.2) or 7.
Otherwise, if you desperately need this fixed, consider either subscribing to an 4.5 ELTS plan or (in case you already have subscribed) get in contact with Anja Leichsenring () and mention this ticket
