Bug description:ImageCreateFromJPEG crashes web server when incorrect image format provided

Description:
------------
Call ImageCreateFromJPEG crashes web server when provided with invalid
image.
In this test scenario http://dl.dropbox.com/u/2807353/phpbugreport.zip
image provided is in PNG format. Image size is 300x300x24. My memory_limit
= 256M ImageCreateFromJPEG should return FALSE when called with invalid
data, instead it crashes web server.

Unhandled exception at 0x7c90108d in httpd.exe: 0xC0000005: Access
violation writing location 0x01547104.

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

// you can download actual image and script from here: 
// http://dl.dropbox.com/u/2807353/phpbugreport.zip

$moo = ImageCreateFromJPEG('img.jpg');

?>

Expected result:
----------------
ImageCreateFromJPEG() should return FALSE not crash webserver

Actual result:
--------------
