Hi,

Installing and learning a whole new platform is not a reasonable ask to try to reproduce a bug.

Please provide a short reproducible scripts as is explained at http://xdebug.org/reporting-bugs

cheers

Thanks, will provide a reproducible script next week!

Moving this back to feedback until I see the short reproducible script.

This small script should make it reproduccible. I thought it was only an issue with PHP 7.4 but just noticed it also affects PHP 8.0.

<?php

class Container
{
    /**
     * @var \ArrayObject
     */
    protected $permissions;

    public function __construct()
    {
        $this->permissions = $this->permissions ?: new ArrayObject();
    }

    public function addPermission(Permission $permission)
    {
        $this->permissions->append($permission);
    }
}

class Permission
{
    private $id;

    public function __construct($id)
    {
        $this->id = $id;
    }
}

$container = new Container();
$container->addPermission(new Permission(1));
$container->addPermission(new Permission(2));
$stop = 1;

I've confirmed this, with an even much smaller test script:

<?php
$permissions = new ArrayObject();
$permissions->append(1);
$stop = 1;

With the breakpoint on the $stop = 1; line.
