IntlDateFormatter crashes (SIGSEGV) when dateType is outside expected range

[mrblur]

Description

The following code:

<?php

$datetime = new \DateTime('2017-05-12 23:11:00 GMT+2');

$formatter = new IntlDateFormatter(
	locale: 'en',
	dateType: -2,
	timeType: 0,
	timezone: $datetime->getTimezone(),
);

var_dump($formatter->format($datetime));

Resulted in this output:

SIGSEGV

But I expected this output instead:

false

PHP Version

PHP 8.1.22

Operating System

No response

Seems to me that since UDAT_PATTERN is passed (-2) for dateType, timeType needs to be too, but I ll have a better look later.
