Opcache does not handle class hoisting with @opcache_compile_file

Description

The following code:

// test.php
<?php

$x = new HelloWorld();

class HelloWorld {}

// exec.php
<?php
@opcache_compile_file(__DIR__.'/test.php');
require_once __DIR__.'/test.php';

When I ran php exec.php it
Resulted in this output:

[30-May-2025 08:10:33 UTC] PHP Fatal error:  Uncaught Error: Class "HelloWorld" not found in /usr/src/wordpress/wp-includes/SimplePie/test.php:3
Stack trace:
#0 /usr/src/wordpress/wp-includes/SimplePie/exec.php(3): require_once()
#1 {main}
  thrown in /usr/src/wordpress/wp-includes/SimplePie/test.php on line 3

But I expected this output instead:

empty as it does not return anything

When just running test.php it runs successfully.

This causes an error in Wordpress file /usr/src/wordpress/wp-includes/SimplePie/autoloader.php when we use Opcache preloading preventing it from working properly.

Inizia riproducendo il comportamento con il test.php e l'exec.php dell'issue usando PHP 8.1.32, quindi traccia come OPcache gestisce opcache_compile_file e il class hoisting. Il lavoro è completato quando il require del test.php compilato non genera più l'errore HelloWorld e lo scenario dell'autoloader di WordPress funziona correttamente.
