If I run PHP 5.5.3 with the compiled opcache.so of 5.5.1 there is no issue. Thus it points to a regression of the opcache code between 5.5.1 and 5.5.2. ------------------------------------------------------------------------ [2013-08-28 21:18:53] ole dot hattebol at swipnet dot se I am trying to configure MediaWiki 1.21.1 and have PHP-5.5.2. Operating system is Windows Small Business Server 2011 Essentials. The web server is IIS 7.5. I get error 500 when I click "set up the wiki" on the configuration start page. I have tried the various recommended permission settings to no help. ------------------------------------------------------------------------ [2013-08-28 07:48:54] i at mudkip dot me I have the same issue with PHP 5.5.2/5.5.3 and MediaWiki 1.21.1 I'm using Arch Linux. Any MediaWiki search request would cause a segfault in php- fpm when opcache is enabled. Sorry I have no time to figure out which part of MediaWiki caused this crash. But when I downgraded the opcache.so to the old version (7.0.2), and still using PHP 5.5.3, this problem could be solved. I believe this is caused by some recent changes of opcache. As for me, I'm now using PHP5.5.3 with this older version of opcache.so ------------------------------------------------------------------------ [2013-08-23 13:29:31] php at cscott dot net Just to be clear: I do not intend to construct the requested test case. I spent my quota of time filing the bug report, in Debian and here. This is a serious regression, hopefully the next person who tries to use mediawiki on 5.5.2 will be able to contribute to minimization. As for me, I just downgraded to 5.5.1 and got back to work. ------------------------------------------------------------------------ [2013-08-23 06:22:36] laruence@php.net Thank you for this bug report.
