Description:
------------
I recently updated to 5.3.6 on a VirtualBox VM that uses a shared directory from 
my Windows 7 (64-bit) machine for project files.  I've since determined that 
DirectoryIterator fails to locate any files in the shared directory.  

Upon further inspection, it works fine for any other directory on the VM.  I've 
also confirmed that the same issue does not happen when going from a Linux machine 
to the VM leading me to believe that this is NTFS-related.

The last known working version was 5.3.3.  Version 5.3.5 had the same issues as 
the current version and I did not test on 5.3.4.

Googling found another person with the same problem:

Test script:
---------------
<h1>DirectoryIterator Test on VirtualBox Shared Folders</h1>
<h2>Passing</h2>
<?php
// Shows files in a non-shared folder directory, change this to a real directory
$pass = new DirectoryIterator('/home/develop/web/');
foreach ($pass as $file)
{
	var_dump($file->getFilename());
}
?>
<hr/>
<h2>Failing</h2>
<?php
// Shows nothing in a shared folder directory, change this to a real directory
$fail = new DirectoryIterator('/home/develop/web/projects/');
foreach ($fail as $file)
{
	var_dump($file->getFilename());
}

Expected result:
----------------
List all of the files in the shared folder directory

Actual result:
--------------
No files are found
