Edit report at https://bugs.php.net/bug.php?id=80307&edit=1 ID: 80307 Comment by: php at shyim dot de Reported by: php at shyim dot de Summary: Segfault in zend_execute when opcache preload enabled Status: Closed Type: Bug Package: opcache Operating System: Ubuntu 20.04 PHP Version: 8.0.0RC3 Assigned To: nikic Block user comment: N Private report: N New Comment: With the built from your Commit anything worked on my side. With RC4 now php-fpm even does not start. It stops with Exit Code 70. Is that known? I can share later a GDB Back trace Previous Comments: ------------------------------------------------------------------------ [2020-11-05 15:39:49] nikic@php.net @michael: I've cherry-picked the fix to the PHP-7.4 branch with https://github.com/php/php-src/commit/6808968c896a18d2b9f309b2fe63d529058b78b4, as I do think it can occur there as well. This will be part of the PHP 7.4.13 release. ------------------------------------------------------------------------ [2020-11-05 14:04:09] michael dot zangerle at gmail dot com To which PHP version as this fix applied? Because in the header and description it says 8.0.0RC ... > PHP Version: 8.0.0RC3 > Tried my Symfony 5.1 project on PHP 8.0RC3, working in 7.4. .. but in the example it says 7.4. > Start web server > /opt/php-7.4/bin/php -S 0.0.0.0:7050 -t . > curl localhost:7050 > > => Segmentation fault... The reason why I am asking is that I am experiencing the same problem with random trait methods being called (as described by nikic) with Symfony 5.1, preloading and PHP 7.4.12. I do not experience this with PHP 7.4.11. ------------------------------------------------------------------------ [2020-11-05 13:11:49] phil at phil-taylor dot com Related To: Bug #80321 ------------------------------------------------------------------------ [2020-11-05 12:03:25] cmb@php.net Related To: Bug #80321 ------------------------------------------------------------------------ [2020-11-05 11:12:10] nikic@php.net Should be fixed by https://github.com/php/php-src/commit/33969c2252b2c33a72c9039072af8862fd347a5f . ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
