The reason is, that GDALCreateGenImgProjTransformer() does not accept source data sources which are not georeferenced. As an ugly workaround, I set the first item in GeoTransform (x offset) to DBL_MIN. In theory it can cause a shift in georeferencing. I don't believe however that it could be really a problem. The shift is 2.22507e-308.
