Description:
------------
My script that uses Imagick extension and has perfectly worked for a couple of years crashes after update PHP 5.1.x on WinXP to PHP 5.3.2 on Win7. 
I found that it crashes silently at the point where I am trying to use image from my D: drive.
I easily reproduced the crash in a separate script with one line only:
<?php $im = new Imagick('D:\image.jpg');?>
If I change it to  <?php $im = new Imagick('C:\image.jpg');?> - it works.

GD's imagecreatefromjpeg() crashes as well, but it troughs an error: 'imagecreatefromjpeg() JPEG library reports unrecoverable error' .

I tried to load the same image from C: drive and it works as it should.
I tried to do "fopen" from D: drive and it works.

The bug appears on Windows 7 environment only. The PHP installed on C: drive.

P.S. sorry, if my English is not very clear.

Test script:
---------------
<?php $im = new imagecreatefromjpeg('D:\image.jpg'); // crashes?>
<?php $im = new imagecreatefromjpeg('C:\image.jpg'); // works?>


Expected result:
----------------
First line crashes.
Second line works.
