Edit report at https://bugs.php.net/bug.php?id=70110&edit=1 ID: 70110 Comment by: stanislav dot khromov at gmail dot com Reported by: bugzilla77 at gmail dot com Summary: preg_match problem Status: Open Type: Bug Package: PCRE related Operating System: * PHP Version: 7.0.0beta1 Block user comment: N Private report: N New Comment: Here is a pull request to bump the maximum stack size to 512K, as recommended by the PCRE docs. https://github.com/php/php-src/pull/2910 Previous Comments: ------------------------------------------------------------------------ [2017-09-04 10:12:11] alec@php.net This just hit us here: https://github.com/roundcube/roundcubemail/issues/5932 And the regex we use is '/^\* (OK|PREAUTH)/i', and this just silently does not match where it should. Please, give it a higher prio. A warning in the log is really needed for such cases. ------------------------------------------------------------------------ [2017-05-31 13:16:45] donatj at gmail dot com As it stands, retuning false is a very bad behavior. We have thousands of regexes in hundreds of code bases that just worked but fail at random in PHP7. Having to now check every single one for JIT stack over flow every single time is a MAJOR hassle. I would have strongly preferred an exception or a warning that would at least automatically shown up in our logs, but right now our existing code bases fail silently which is the worst of all worlds. ------------------------------------------------------------------------ [2017-05-03 11:31:45] mk at bio dot logis dot de Just want to point out that Drupal's and Symfony's YAML parsing are affected by this bug as well: https://www.drupal.org/node/2792877 ------------------------------------------------------------------------ [2017-05-03 11:23:14] cmb@php.net Thanks for the reminder – I don't have time for this, though. ------------------------------------------------------------------------ [2017-05-03 10:01:02] hristochonov at gmail dot com cmb@php.net has commented on [2015-08-25 23:56 UTC]: "Further improvements have to be postponed until PHP 7.1 at least, so I'm suspending the ticket for now." PHP 7.1.0 has been released on 01 Dec 2016. It will be great if it would be possible to bring the issue forward now. We are experiencing this bug pretty often and have to always manually turn off PCRE-JIT in code for known regular expressions going to crash. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
