This is a test repository with a PHP 8.1 segfault problem

Steps to reproduce:

1. Install deps: docker run --rm -v ${PWD}:/app -w /app composer install

2. Run the test code on PHP 8.0 to be sure there is no problem with it: docker run --rm -v ${PWD}:/app -w /app php:8.0-cli vendor/bin/phpunit -vvv Test.php; echo $?

❯ docker run --rm -v ${PWD}:/app -w /app php:8.0-cli vendor/bin/phpunit -vvv Test.php; echo $?
