Hi list!

The following attempt segfaults on GRASS 6.4.3svn (nearly in the end of the 
process, if I am not wrong), running on Core i7 with 32GB of RAM.

# mdenoise ASTER GDEM2 over Greece
r.denoise in=aster_gdem2_ellas out=aster_gdem2_ellas_smoothed iterations=1 
threshold=0.8 epsg=2100

The computational area comprises (Rows: 32401, Columns: 36001) 1166468401 
cells.  Is this too much?

Would (re-)running this on GRASS 7.0.svn make any difference?
I should better perform the process on a per (ASTER GDEM2) tile(s) basis, 
shouldn't I?

Thank You, Nikos
