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

Issue: https://github.com/php/php-src/issues/7817 Comment Author: dstogov @meinemitternacht the fact that the problem doesn't happen consistently, very probably tells about some race condition. e.g. one process is writing something into shared memory (and somehow gets into inconsistent state), at the same time anther process reads from SHM and somehow fails because of inconsistency. The failure occurs only because of luck, when both processes gets into specific states. I think, there is no difference between fresh OS reboot, or PHP-FPM restart (both recreate SHM). PHP CLI doesn't share memory with PHP-FPM.
