Bug #79231 [NEW]: Segfault when preloading via php-fpm

From: brent at spatie dot be Operating system: Ubuntu 18.04.3 LTS PHP version: 7.4.2 Package: opcache Bug Type: Bug Bug description:Segfault when preloading via php-fpm Description: ------------ I've been trying out preloading, and am running into a segfault using PHP 7.4.2, only when using php-fpm. I've been using this preload script: https://github.com/brendt/aggregate.stitcher.io/blob/master/preload.php When using this preload script via PHP's built-in webserver, all works fine. For reference, this is the command I used to test this: `php -c /etc/php/7.4/fpm/php.ini -S aggregate.stitcher.io:8001 -t public -d opcache.preload=preload.php -d opcache.user=forge` However, when using the same preloading script via php-fpm, a segfault occurs. Here's a snippet from the php-fpm logs, this message gets repeated over and over again: ``` [05-Feb-2020 12:06:01] WARNING: [pool www] child 2961 exited on signal 11 (SIGSEGV - core dumped) after 0.942953 seconds from start [05-Feb-2020 12:06:01] NOTICE: [pool www] child 2972 started [05-Feb-2020 12:06:01] WARNING: [pool www] child 2963 exited on signal 11 (SIGSEGV - core dumped) after 0.947206 seconds from start [05-Feb-2020 12:06:01] NOTICE: [pool www] child 2977 started [05-Feb-2020 12:06:01] WARNING: [pool www] child 2965 exited on signal 11 (SIGSEGV - core dumped) after 1.009507 seconds from start [05-Feb-2020 12:06:01] NOTICE: [pool www] child 2979 started ``` Checking php-fpm's status using sudo service php7.4-fpm status after restarting it, I get the following output: ``` … Feb 05 12:04:42 brent php-fpm7.4[2039]: [Preloader] Preloaded Illuminate\Mail\TransportManager Feb 05 12:04:42 brent php-fpm7.4[2039]: [Preloader] Preloaded Illuminate\Mail\Markdown Feb 05 12:04:42 brent php-fpm7.4[2039]: [Preloader] Preloaded 1127 classes Feb 05 12:04:42 brent systemd[1]: Started The PHP 7.4 FastCGI Process Manager. ``` So php-fpm manages to start, it only crashes as soon as a request arrives at the server.
