Maybe I have to file a bug report to the maintainer of the package. (I use the default packege for ubuntu 14.04 LTS) then forget my bt and use majo-bugs's bt But this error is hard to reproduce because it only happens on many requests. Bofore I had have opcache enabled and got many fatal error that a function can not be redeclared. But I checked the code many times. Even with require_once and check if function_exists(). Then I disabled opcache and since then I get seg faults. I use Apache mpm-prefork and have tried to use different configs (reduce MaxConnectionsPerChild...) but it didn't solve anything. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
