I hope this is OK, you can find it here: https://github.com/jgroth/php-crash Something I found interesting while removing as much code as possible from my application was that I could not remove comments for some methods in some of the classes/interfaces. Doing so would not reproduce the bug. Also, when I turned off error reporting, I did not get the bug either. Note that there is one "Notice" error reported by PHP in this test application. I do not have any such errors in the full application, but still got a php crash. ------------------------------------------------------------------------ [2012-10-20 04:39:27] larue...@php.net great, if it's okey, you can tar your application as a reproduce script for us ------------------------------------------------------------------------ [2012-10-19 12:35:49] johan dot groth at sorona dot se Ok, so I have somewhat been able to reproduce the problem. I can still not do it in a small script, but I have been able to remove enough code from my application so I can send it to anyone who might be looking into this issue. The application is based on CodeIgniter, so it's basicly the CI code + a few extra files from my application. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
