[php-src] Issue #11736: JIT cause 100% cpu usage

Issue: https://github.com/php/php-src/issues/11736 Author: andrii29 ### Description The following code: ```php [opcache] opcache.enable=1 opcache.enable_cli=1 opcache.memory_consumption=512 opcache.jit_buffer_size=256M opcache.interned_strings_buffer=16 opcache.max_accelerated_files=200000 opcache.max_wasted_percentage=5 opcache.use_cwd=1 opcache.validate_timestamps=0 opcache.revalidate_freq=600 opcache.revalidate_path=0 opcache.save_comments=1 opcache.enable_file_override=0 opcache.optimization_level=0x7FFFBFFF opcache.dups_fix=0 opcache.max_file_size=0 opcache.consistency_checks=0 opcache.force_restart_timeout=180 opcache.file_cache_only=0 opcache.file_cache_consistency_checks=1 opcache.huge_code_pages=1 opcache.preload=/path/to/config/preload.php opcache.preload_user=user ``` Resulted in this output: ``` [18-Jul-2023 03:40:09] NOTICE: [pool www] child 179 started Fatal error: Maximum execution time of 99+2 seconds exceeded (terminated) in /path/to/file.php on line 33 [18-Jul-2023 03:40:13] WARNING: [pool www] child 47 exited with code 124 after 381.082060 seconds from start [18-Jul-2023 03:40:13] NOTICE: [pool www] child 182 started Fatal error: Maximum execution time of 99+2 seconds exceeded (terminated) in /path/to/file.php on line 33 [18-Jul-2023 03:40:25] WARNING: [pool www] child 42 exited with code 124 after 393.292804 seconds from start ``` But I expected this output instead: ``` no errors in log ``` Hello, after enabling JIT, our application start perform better (~10% faster). But, some php-fpm pods (~1 in 20) after start use all available cpu and timeout the requests. After pod restart, everything back to normal. Without JIT everything is ok and cpu utilization is at normal value.
