That was to test if the problem was with the PCRE2 code in general or if it was specifically about
how ext/filter and FILTER_VALIDATE_REGEXP uses it.

@mlocati, excellent! I'll add it as a test.
@requinix your snippet doesn't repro, unfortunately.
Thanks.

What happens with this?
<?php
$text = '{CCM:CID_2}';
echo '1';
preg_replace_callback(
'/([0-9]+)/i',
function ($matches) {
echo $matches[1];
preg_match('/^http$/i', '');
},
$text
);
echo '3';

PS: I'm on Windows, so -1073741819 is the 0xC0000005 (STATUS_ACCESS_VIOLATION) system error
