Description

Description

Got the following assertion when running multiple Psalm unit tests: https://github.com/danog/php-src/actions/runs/11871508040/job/33084124984#step:10:10289

php: /home/runner/work/php-src/php-src/Zend/zend_alloc.c:2945: tracked_get_size_zv: Assertion `size_zv && "Trying to free pointer not allocated through ZendMM"' failed.

Config is in https://github.com/php/php-src/pull/12406, reproducer command is:

php --repeat 2 -f .github/jit_check.php /tmp/psalm/vendor/bin/phpunit /tmp/psalm/tests/ProjectCheckerTest.php
PHP Version

Research direction

Start with the assertion at Zend/zend_alloc.c:2945 and reproduce it using the provided php --repeat command with .github/jit_check.php and Psalm's ProjectCheckerTest.php. Trace the failing allocation path and verify that the Psalm unit tests complete without the ZendMM assertion.
