Description:
------------
Running our internal testsuite in with php7 (master git up-to-date) in a normal build works fine, with --enable-debug with get the following error:

php: /home/arjen/phpng/php-src/ext/spl/spl_directory.c:966: zim_spl_DirectoryIterator_getExtension: Assertion `p > fname->val' failed.

If it fails, the currenct DirectoryIterator entry is a '.' entry.

Test script:
---------------
<?php

$it = new DirectoryIterator(__DIR__);

foreach ($it as $entry)
{
	var_dump($entry->getPathname(), $entry->getExtension());
}

Expected result:
----------------
No assertion. Empty string for directory entries without extension:

"Returns a string containing the file extension, or an empty string if the file has no extension."

Actual result:
--------------
php: /home/arjen/phpng/php-src/ext/spl/spl_directory.c:966: zim_spl_DirectoryIterator_getExtension: Assertion `p > fname->val' failed.
