Bug #70023 [NEW]: PHP SegFaults when optimization pass 1 is enabled

From: FractalizeR at yandex dot ru Operating system: CentOS 7 PHP version: 5.6.10 Package: opcache Bug Type: Bug Bug description:PHP SegFaults when optimization pass 1 is enabled Description: ------------ When at least optimization pass 1 (bit 0 of opcache.optimization_level) is enabled in Zend Optimizer, PHP 5.6.10 segfaults on some yet unknown piece of my PHP code with the following backtrace. I still cannot locate the responsible piece of my code, which leads to crash (I use Laravel framework and project codebase is not small). Is there any way to figure out PHP script backtrace when segfault happened? Segfault seem to happen only when I run several requests to the same page in parallel (at least two) because php segfaults only with "ab -n 120 -c 2" and DOES NOT segfault with "ab -n 120 -c 1".
