Bug #79931 [NEW]: Segmentation fault
From: contact dot obukhov at gmail dot com
Operating system: Debian Buster
PHP version: 7.4.8
Package: Reproducible crash
Bug Type: Bug
Bug description:Segmentation fault
Description:
------------
I am using Symfony 5 and Doctrine and face Segmentation fault on some
requests, when about 30-40 records are loaded from database (MySQL
5.7).
Because this is segmentation fault and doctrine code looks OK it seems
to be a bug in PHP.
We used 7.4.6, upgraded to 7.4.8 but problem still occurs. We can not
test it in 7.3 because of typed properties we use almost everywhere.
Environment is Docker container from official image
php:7.4.8-fpm-buster
php -i

valgrind --tool=memcheck --num-callers=30 --log-file=php.log
--suppressions=php.supp php bin/console s:t:g:

What is weird with USE_ZEND_ALLOC=0 it does not crash
USE_ZEND_ALLOC=0 valgrind --tool=memcheck --num-callers=30
