[GRASS-user] r.terraflow usage (segfault)

[Massimo Di Stefano]

Hi

i'm tring to use "r.terraflow"

following the help page i see :

r.terraflow elev=spearfish filled=spearfish-filled \
     dir=spearfish-mfdir swatershed=spearfish-watershed \
     accumulation=spearfish-accu tci=spearfish-tci


but i can't find any "spearfish" elevation data in the spearfish dataset
so i used elevation.dem insted, but i've a segfault :-/

i tried with different locatiuon too, using:
as data input an elevetion model (230m resolution)
in a wgs84 UTM 33 N location

but i have segfault again....

mybe my knowledge of the r.terraflow application is not so good, and  
i'm missing something to prepare the input data ?

i tried the same step having the same results
on a grass64 svn builded from source on different platforms
(ubuntu 8.04 32 bit , osx 10.5)


thanks for any help!

regards,

Massimo Di Stefano.
