Description

Got the following assertion when running multiple Psalm unit tests:

ext/opcache/jit/zend_jit_ir.c:1386: zend_jit_use_reg: Assertion `jit->ra[var].flags & (1<<0)' failed.

Config is in #12406, reproducer command is:

php --repeat 2 -f .github/jit_check.php /tmp/psalm/vendor/bin/phpunit /tmp/psalm/tests/LanguageServer/FileMapTest.php

PHP Version

nightly

Operating System

No response

This may be fixed via ef5844a

I wasn't able to reproduce the reported assertion, but got a crash instead.
The commit above fixed the crash. Assertion is not reproducible.

@dstogov Thanks! Seems okay, but still getting some segfaults on tests/AnnotationTest.php and several others (currently testing on arm64).

Reproduce by cloning and running php .github/nightly.php with the following ini:

zend.assertions = 1
display_errors = On
display_startup_errors = On

@dstogov Sorry, I meant to link the repo https://github.com/danog/php-src for the reproducer :)
