Squeak VM Win32 crash

Hi all,
I have a reproduceable VM crash of Win32 Squeak VM version 4.1.1 (also
with 4.0.2).
The crash from my tests seems to be related to the size of the JPEG
image being loaded.

I downloaded locally images at [1] (image1) and [2] (image2).
I was previewing them with DesktopBackgroundLoader [3],
when I select image2 I am able to preview it, but when I select image1
the VM crashes.

Initially I was thinking at a bug in the JPEG Plugin but
the surprise is that when I do the same with FileList there is no crash!!!
Of course the two pieces of code are different...

I have no clue on how to proceed so I post it to see whether somebody
else can reproduce
it as well and maybe dig further.

Bye
Enrico

To add more info:
I repeated the same experiment on Mac OSX 10.6.4
with VM 4.2.5beta1U and found no problems at all.

So it seems platform specific.

This is the same as open issue http://bugs.squeak.org/view.php?id=7523, with identical crash dump.....

With Cog it doesn't crash! When I run the croquet cog vm with the image provided by Andreas, I can't make it crash on (variants of) this code:

| dir files slash result |
        dir := 'f:\squeak3'.
        files := (FileDirectory on: dir)  fileNamesMatching: '*.jpg'.
        slash := FileDirectory slash.
        result := OrderedCollection new.
        20 timesRepeat: [result addAll: (files collect: [:each | Transcript cr; show: each. ImageReadWriter formFromFileNamed: dir , slash , each])]

With the trunk image and Squeak4.0.2.exe it invariably crashes.....

I tried to reproduce this crash in Cog but couldn't.  You might test too using cogwin.zip <http://www.mirandabanda.org/files/Cog/VM/VM.r2219/cogwin.zip> .  If it doesn't crash then it's either a difference between the standard platforms JPEG plugin files and the Cog platforms JPEG plugin files (unlikely) or a difference between gcc 2.95 (standard VM) & gcc 3.4.4 (Cog).
