Iterating on ResourceBundle (using keys) causes segmentation fault

[KidFlo]

Description

The following code:

<?php
foreach ((new ResourceBundle('', NULL))->get('calendar')->get('buddhist') as $key => $value)
    ;

Resulted in:

(segfault)

But I expected:

(no segfault)

On my Windows machine (ICU 75.1), but not only (apparently).
