[php-src] Issue #7817: JIT segmentation fault in PHP 8.1

Issue: https://github.com/php/php-src/issues/7817 Comment Author: meinemitternacht @dstogov Can you provide a short explanation of how the shared memory space works with JIT? I usually see the problem occur after a fresh reboot, but it still does not happen every time. My first goal is to get the issue to happen consistently then I can narrow down the code that is causing the segfault. Basically, my question is, what is the difference between an OS reboot and restarting php-fpm? Does the OS cache libraries, or should I watch out for shared memory between the PHP CLI and php-fpm? I am using the CLI opcache.
