### Description The following code: <?php $fmt = datefmt_create('fr_CA', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Toronto', IntlDateFormatter::GREGORIAN); Resulted in this output: No response from request as Windows Apache has crashed with access violation But I expected this output instead: no problem The problem seems related to the new included version 75 of ICU DLL. If I download the same DLL from GITHUB, the problem is fixed. Was downloaded from: https://github.com/unicode-org/icu/releases/tag/release-75-1 The problem started to appear with 8.4-RC4 ### PHP Version PHP 8.4 ### Operating System Windows 11 with Apache server
