PHP-CS-Fixer: 2.16.8 crash because of symfony/polyfill-mbstring

Bug report

I’m using php 8.0.0 with mbstring extension loaded. I know php8 is not fully supported at the moment but it works pretty well with previous cs-fixer release and env var PHP_CS_FIXER_IGNORE_ENV=1.

PHP needs to be a minimum version of PHP 5.6.0 and maximum version of PHP 7.4.*.
Ignoring environment requirements because `PHP_CS_FIXER_IGNORE_ENV` is set. Execution may be unstable.

Ah sorry everyone. Someone on the PR made the false assumption that PHP 8 is now supported on PHP CS Fixer which I didn’t verify myself. My bad!

Hi @driesvints , The issue in your sample is running the tool on PHP8 which is not officially supported yet, it is not related to the issue discussed here. For more info on the process on PHP8 support and how to help out please check out https://github.com/FriendsOfPHP/PHP-CS-Fixer/issues/4702

I can confirm that the 2.17.1 PHAR works flawlessly on PHP 8. Thank you very much for the quick fix! ❤️

I’ll try to find some time tonight. I’m pretty sure though that this has to be fixed not in this repository but in the polyfill’s.

This seems to be an issue with the PHAR distribution of PHP CS Fixer 2.16.8. The PHAR of 2.16.7 works fine and if I install 2.16.8 via composer as a dependency of my project, ./vendor/bin/php-cs-fixer also works fine.
