> Subject: ps.map segfaults with CELL rasters withouth cat file
..
> GRASS Version: grass-6.0.cvs_src_snapshot_2005_02_12
> 
> When the raster has an empty catfile like:
> 
> ---
> # 255 categories
> 
> 
> 0.00 0.00 0.00 0.00 
> ---
> 
> and in section "colortable" the "nodata n" is specified, ps.map
> segfaults as following:
> 
> GRASS 6.0.cvs:~ > ps.map input=ps2.txt output=map1.ps
> PS-PAINT: scale set to 1 : 347440.
> PS-PAINT: reading raster file <gminy in robot> ...
> PS-PAINT: outlining areas in raster file <gminy in robot> ...
> PS-PAINT: creating color table for <gminy in robot> ...Segmentation
> fault
> 
> It doesn't segfault when the "no data n" is not specified.
> 
> I think that in both cases an info should be printed like "WARNING:
> Your catfile is invalid. A catfile with categories and labels is
> required for colortable in case of CELL rasters. No colortable will be
> assigned to this output postscript file."


fixed in CVS, warning added.
