The following code:

MessageFormatter::parseMessage() with invalid locale
--EXTENSIONS--
intl
--FILE--
<?php

$locale = 'root';
$fmt = '{0,whatever} would not work!';

$str = 'failing';

$m = MessageFormatter::parseMessage($locale, $fmt, $str);
var_dump($m);
var_dump(intl_get_error_message());

$m = msgfmt_parse_message($locale, $fmt, $str);
var_dump($m);
var_dump(intl_get_error_message());

?>
