https://3v4l.org/4MTF2

Bug present from PHP 7.4, prior versions are not affected

Test script:
---------------
class MyArrayIterator extends \ArrayIterator
{
    private $foo = 'bar';
}

$ai = new MyArrayIterator([]);
var_dump(count($ai));
var_dump($ai->current());
var_dump(current($ai));

Expected result:
----------------

NULL
bool(false)
