[php-src] Issue #11127: JIT fault

Issue: https://github.com/php/php-src/issues/11127 Author: EvgenijKrupchenko ### Description This bug was accidentally noticed in complex production scripts and was very hard to manually reproduce in a simple example. But nevermind, here's a working example below. I use two files: 1.php: <? include('2.php'); for($a=1;$a<100;$a++){ echo _f('1'); echo _f('1'); echo _f('1'); } ?> 2.php: <? define('C',['1']); function _f($u){ return $u==C?'0':'1'; } ?> In short: the script is using multiple times a function, that is located in another php script file. Under php 8.2, 8.1 and 8.0 - same results. Under php-fpm and under apache/mod_php - same result. Under php-cli - bug not reproducible Steps to do: 1) Restart the backend (php-fpm or apache/mod_php) 2) Open in browser 1.php - works fine 3) Make any changes to 2.php or simply run "touch 2.php" to only modify the time of that file 4) Refresh the page with 1.php - Nginx (frontend) says "502 Bad Gateway" with log: upstream prematurely closed connection while reading response header from upstream Apache error log empty. Php-fpm error log says something like: [24-Apr-2023 18:21:07] WARNING: [pool u10] child 71477 exited on signal 11 (SIGSEGV) after 20.735545 seconds from start [24-Apr-2023 18:21:07] NOTICE: [pool u10] child 71484 started php.ini: opcache.jit_buffer_size=128M When only i add: opcache.jit=1205 The bug disappear, but php performance become a bit slower. And also setting opcache.jit_buffer_size=0 solves the bug as well as slowing down the performance of course. I have no clue what's going on, but something is clearly becomes wrong causing the executing process to crash. ### PHP Version php 8.2.5 8.1.18 8.0.28 ### Operating System Debian 11
