permenently segfaults until i stop to load opcache the really strange is that with "ab -c 100 -n 50000" i am unable to reprocude a single segfault, sometimes depending on luck also not with browsing, the next time nearly any request is answered with a Firefox error that the server unexpectly closed the connection Test script: --------------- currently i have no easy test-script, only cms pages and complexer libraries used and as said: it may take hours to reproduce and in other cases i update a production server to PHP > 5.5.6 and it gets terrible unstable shortly after restart httpd ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66460&edit=1
