JIT leak in Symfony TranslationDebugCommandTest

[iluuu1994]

Description

We get a new JIT leak in the COMMUNITY build for Symfony on PHP 8.1. https://github.com/php/php-src/actions/runs/6413467433/job/17412450113 This is exposed due to the config changes introduced in #12250.

Direct leak of 112 byte(s) in 2 object(s) allocated from:

I was able to reproduce this locally with the following command:

php-dev -d opcache.enable_cli=1 -d opcache.jit=tracing -d opcache.jit_buffer_size=1G -d opcache.jit_max_root_traces=1000000 -d opcache.jit_max_side_traces=1000000 -d opcache.jit_max_exit_counters=1000000 -d opcache.jit_hot_loop=1 -d opcache.jit_hot_func=1 -d opcache.jit_hot_return=1 -d opcache.jit_hot_side_exit=1 -d memory_limit=-1 ./phpunit src/Symfony/Bundle/FrameworkBundle/Tests/Command/TranslationDebugCommandTest.php --exclude-group tty,benchmark,intl-data,transient --exclude-group skip

The leak occurs when running $tester->execute() twice, it's not triggered if only running a single test. However, you can also reproduce it by running --filter testDebugMissingMessages and duplicating that line. Unfortunately, I was not able to build a simple reproducer given that the Symfony code is quite complex. It might be possible to produce one once we understand the root problem.
