Bug #74596 [NEW]: SIGSEGV with opcache.revalidate_path enabled

From: stephan dot muggli at googlemail dot com Operating system: Debian GNU/Linux 8 PHP version: 7.1.5 Package: opcache Bug Type: Bug Bug description:SIGSEGV with opcache.revalidate_path enabled Description: ------------ Hi, I have encoutered a problem with our application and PHP 7.1.x with opcache enabled. After some research I found out that the option "opcache.revalidate_path" costs the segfault when it is enabled. Disabling the option solves the problem for now. I tried to find the code which brings up the segfault but the only thing I got is that it seems to be a problem with https://github.com/goaop/framework.
