The raster layer "land_shallow_topo_2048" in tomk_workshop is not projected
correctly on Linux compared to Windows.  The projection is set correctly (  
"init=epsg:4326") in the layer and in the map file.  I tested on MS beta 3 on
both OS.  I will attached files for comparison.

The simple way to reproduce this is to execute the following command:
shp2img -m tomk_workshop.map -o map.png

Could you have a look at this bug Tom?

Normand: can you contact me offline via email to help me checkout msautotest? 
I'll take a look at things

Tom's answer:

The problem is the TIFF image in
msautotest/wxs/data/land_shallow_topo_2048.tif.

The accompanying .wld file is defined for an image of 2048 x 1024.  The
image in the CVS is 512 x 256.

So, there are two options you can take:

1./ fetch the actual (2048 * 1024) image from the MS OGC Web Services
workshop from http://ms-ogc-workshop.maptools.org/, remove the old image
and replace it with the large one

OR

2./ the image may have been shrunk in the interest of size.  Because
it's cut down by a factor of 4, multiplying the x/y coords in the .wld
file will render the image correctly.

I have tested with the following .wld file:

0.703125
0.0
0.0
-0.703125
-180
90

And all works fine.

I will go for option 2.  Fixed in CVS.

Frank's comment:

Guys,

Thanks for taking this option.  It is my intention that the msautotest
datasets be pretty small.  Dealing with FDO (part of MapGuide) and it's
enourmous test datasets in source control has once again convinced me
that keeping test datasets smallish is valuable!
