Description:
------------
Storing all DirectoryIterator objects fetched previously with an instance of DirectoryIterator within an array seems to make stored objects to lose all data.

While methods like 'isDir()' work fine in first loop, they will always fail within second loop.

Test script:
---------------
<?php
$array = array();
$dir = 'C:/inetpub/wwwroot/di/';

$it = new DirectoryIterator($dir);
foreach ($it as $obj) {
	if ($obj->isDot()) continue;
	var_dump($obj);
	if ($obj->isDir()) echo $obj->getFilename() . ' is a directory.<br />';
	else echo $obj->getFilename() . ' is a file<br />';
	
	$array[] = $obj;
}

echo '<hr />';

foreach ($array as $obj) {
	var_dump($obj);
	if ($obj->isDir()) echo $obj->getFilename() . ' is a directory.<br />';
	else echo $obj->getFilename() . ' is a file<br />';
}
?>
