I constructed an input file that is fairly similar to yours and tried
a similar warp and did not encounter this problem.  Can you make your file
available for me to test with?  I suspect there is a problem with the way
your software is setup. Perhaps the coordinate system dictionary is not
being found.

You might get more information if you enable debug output:

   gdalwarp -t_srs EPSG:3763 ROI_QB_MUL_2.tif out.tif --debug on
