Calling gdalwarp.ProjectRasterFile("C:\Programme\Thuban\Data\iceland\island.tif"
,
"+proj=latlong +to_meter=0.017453 +ellps=clrk66 ","+proj=utm +zone=27 +ellps=clrk66 "
,(0.0, -287.0, 363.0, 0.0),[0, 0],(363, 287),1)

Here is the similiar output from a GNU/Linux version:

Calling gdalwarp.ProjectRasterFile("/mobilehome/bernhard/hacking/thuban/root/trunk/thuban-debug/Data/iceland/island.tif",
"+proj=latlong +to_meter=0.017453 +ellps=clrk66 ","+proj=utm +zone=27 +ellps=clrk66 "
,(322003.1320390497, 6979739.6902664267, 876022.18918293528, 7444824.1092898464),[0, 0],(380, 319),5)

So the infection has happened earlier 
as the extend values are significantly different.


Check _transform_bbox

Windows:

Entering _transform_bbox <bound method Projection.Forward of Universal Transverse Mercator: ['proj=utm', 'zone=27', 'ellps=clrk66']> 
(-38.083834311187623, 0.0, 0.0, 393.99339649767938)
(-1430038.2379767266, 0.0, 1.#INF, 1.#INF)

GNU/Linux:
Entering _transform_bbox(<bound method Projection.Forward of Universal Transverse Mercator: ['proj=utm', 'zone=27', 'ellps=clrk66']>,(-24.549588538116822, 63.282272361329014, -13.491440877527877, 66.565551332131932))
...will return  322003.132039 7021768.75421 876022.189183 7402795.04535

Hmm, this function seems to want geographic coordinates and
on Windows there is 393 which is not a legal value.
