Description:
------------
   I found a problem when php recongize a jpg file.This file can be rendered by acdsee,ie,firefox,etc,but getimagesize function returns false.
   Your can download the file from url http://bm.ahtvu.ah.cn/img/20163/a/6/5177/org_faceimg.jpg.
   This file have a lot of zeros between jpg data sections,I check php source code and find that php_next_marker function can not cope with it.
   I give the following patch which I can not ensure ok under any circumstances.

[root@cache84 standard]# diff image.c patch_image.c 
416c416
<       } while (marker == 0xff);
---
>       } while (marker == 0xff || marker == 0);


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

var_dump(getimagesize('/root/f.jpg'));

That appears to be a duplicate of bug #72278, which has been
fixed, but the fix has not yet been released.

Can you please confirm with a current Git snapshot of PHP?
