Crashing on arguments with default value self::class #4713
Description
Bug report
PHPStan crashes when trying to parse code with arguments having default value set to self::class.
<?php
class Service
{
public static function createInstance(string $class = self::class): Service
{
return new $class();
}
}
$service = Service::createInstance();Internal error: Failed to find parent class of constant "class". Run PHPStan with --debug option and post the stack trace to: https://github.com/phpstan/phpstan/issues/new?template=Bug_report.md
This seems to be related to #4288, but not exactly.
