Bug #77937 [Nab->ReO]: preg_match failed

Edit report at https://bugs.php.net/bug.php?id=77937&edit=1 ID: 77937 Updated by: cmb@php.net Reported by: v-altruo at microsoft dot com Summary: preg_match failed -Status: Not a bug +Status: Re-Opened Type: Bug Package: PCRE related Operating System: Windows 10 PHP Version: 7.3.5RC1 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: Thanks for reporting! I can reproduce the *test* *failure*. The problem is that setlocale()[1] claims to support "pt_PT", but actually it does not. Actually supported locales would be "pt-PT" and "portuguese". I'm not sure yet what to do about this. Simply fixing the test case for Windows would be an option, but that would not fix the underlying issue which may affect existing userland code.
