Description:
------------
When trying to use opendir() with ftp:// wrapper ( without trailing slash ) php segmentation faults. Would have expected an error message from opendir().


Sounds like http://bugs.php.net/bug.php?id=386 which is fixed..?

Reproduce code:
---------------
<?php
$url = 'ftp://anonymous:anonymous@ftp.no.freebsd.org';
$dir = opendir ( $url );
var_dump ( $dir );
?>


Expected result:
----------------
opendir() should return error.

Actual result:
--------------
PHP crashes.

wrong username/password gives also the same error even with trailing slash i.e.
$url = 'ftp://foo:bar@ftp.no.freebsd.org/';
$dir = opendir ( $url );
var_dump ( $dir );
