[php-src] Issue #9407: Eval'd code with static return type wrongly overriden do not show correct message

Issue: https://github.com/php/php-src/issues/9407 Author: shavounet ### Description This might be only an issue in the error message since I didn't find any issue with a valid eval'd code. It's quite minor, but I did loose some time trying to understand it :) The following code: ```php <?php class Request { public function duplicate(): static { return new Request; } } class TestGenerator { public static function generate(): void { $code = <<<PHP class MockRequest extends Request { public function duplicate(): Request { return new MockRequest; } } PHP; eval($code); } } TestGenerator::generate(); $b = new MockRequest; $b->duplicate(); ``` Resulted in this output: ``` PHP Fatal error: Declaration of MockRequest::duplicate(): Request must be compatible with Request::duplicate(): TestGenerator in var/test.php(20) : eval()'d code on line 2 ``` But I expected this output instead: ``` PHP Fatal error: Declaration of MockRequest::duplicate(): Request must be compatible with Request::duplicate(): static in var/test.php(20) : eval()'d code on line 2 ``` With a correct eval'd code (static return type), I do not have issues. With a bad not-eval'd code, I do have a correct error message. I can reproduce it with self and parent return types. ### PHP Version PHP 8.1.9 ### Operating System _No response_
