[GRASS-dev] r.in.gdal problems

[Laura Toma]

Hi,

I imported a large SRTM grid with r.in.gdal;  when starting grass64  
with this location there is an error.
Some part of Grass seems to work despite this error, except d.rast  
shows a blank screen.  The east and west (see below)  have the same  
value, except E/W. Could this cause troubles?
