Gambin,

I did:

gdal_translate 080003dv_gauss.tif -gcp 0 0 5409006.4226 4970689.5864
-gcp 0 5931 5409006.4226 4970064.7150 -gcp 7590 0 5409806.0064
4970689.5864 -gcp 7590 5931 5409806.0064 4970064.7150 gcps.tif

gdalwarp -tps gcps.tif warped.tif

After this process, the warped.tif overlays the gcps.tif properly in OpenEV.

Egads, I think I have mixed up your bug report, and the data
from another fellow!  Ignore what I said before about having
already downloaded your file.

Best regards,
