Sounds like it happens only with the 5.3 VC6 versions of our builds.
Which webserver and SAPI do you use?

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