[GRASS-windows] r.los crashes

[iomeneandrei]

Hi all,
I'm usign WinGRASS-6.3.0-4, and I have some difficult with visibility
(r.los) analysis.

When I run r.los using location of mine, r.los crashes.
I use this command:
r.los input=dem at debug output=visibilita coordinate=303778,4210733
obs_elev=1.75 max_dist=10000

If I set max_dist to a lower value (i.e. 1000) I have no crash.

This is my location:
http://www.nabble.com/file/p20457630/castdecimale.zip castdecimale.zip 

This is the error I have:
http://www.nabble.com/file/p20457630/r.los.jpg 

What about this crash? What am I doing wrong?

Thank you,

a
