Bug #81630 [NEW]: PHP 8.1: ReflectionClass->getTraitAliases() crashes with Internal error

From: ondrej at mirtes dot cz Operating system: N/A PHP version: 8.1.0RC6 Package: Reflection related Bug Type: Bug Bug description:PHP 8.1: ReflectionClass->getTraitAliases() crashes with Internal error Description: ------------ Unfortunately I don't have a simple reproducing script here, but I know there's a bug in ReflectionClass when asking for trait aliases. A code that executes the same methods crashes when I run it in context of PHPStan: https://3v4l.org/oSI4m The error message is: Uncaught Error: Internal error: Failed to retrieve the reflection object in phar:///var/www/html/vendor/phpstan/phpstan/phpstan.phar/src/Reflection/Php/PhpClassReflectionExtension.php:576 #0 phar:///var/www/html/vendor/phpstan/phpstan/phpstan.phar/src/Reflection/Php/PhpClassReflectionExtension.php(576): ReflectionClass->getTraitAliases() #1 Maybe it's related to some internal state of ReflectionClass or maybe the way how it was obtained, but calling ReflectionClass->getTraitAliases() always results in a crash on PHP 8.1. It works on PHP 8.0. Hopefully this gives you enough information to track it down.
