------------ 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.
