Segmentation fault with PHP 8.3.20 #18339

Description

The following code:

<?php

$interval = new \DateInterval('PT0S');
$unit = 'h';
$interval->$unit += 0;
var_dump($interval->h);

https://3v4l.org/XP384#v8.3.20

Resulted in this output:

Segmentation fault

But I expected this output instead:

0

(Result we get from PHP 8.3.19 and 8.4.6)

It's possibly the root cause of #18337

PHP Version

8.3.20

Operating System
