Hi devs,
I have 2 rasters:

when I do r.volume with these rasters, I get:
r.volume --verbose input=sample_tallard_eu_dem_westernalps_slope
clump=sample_tallard_eu_dem_westernalps_basin
ERROR: Die Leseanfrage der Rasterkarte

the computational region:
g.region -p -a raster=eu_dem_westernalps at westernalpsriver

align=eu_dem_westernalps at westernalpsriver

nsres: 25
ewres: 25
rows: 4713
cols: 4808
cells: 22660104
any idea what causes such an error?
r.volume, tested with a lot of other rasters of different extents, worked so
far ...
