[GRASS-dev] Segmentation fault with r.cost in grass7.0

[Pietro Zambelli]

Hi all!
I'm Pietro and this is my first message here! So be patient if my information is 
lacking in something. 

I try to run r.cost on grass70 from svn but I have this output message:

GRASS GIS 7.0 svn:40557-40571
===================
$ r.cost -k input=dtm_dist at trentino output=provarcost70

Grass6.4 work fine! And I get this:

GRASS GIS 6.4.0RC5
