winGRASS 6.4.0RC2 and r.los

[iomeneandrei]

Dear all,
I have tested an old bug of grass for windows, and I have it again in this release. It's related to r.los.
When I run this command, grass crashes:
r.los input=DEME@andrea output=tr_vis coordinate=300000,4210000 obs_elev=1.75 max_dist=10000

If I have a smaller max_dist (1500) I have no error.

I have this bug in win xp 32 bit and not in vista 64 bit.

ciao,

a

I am afraid to say that either you or another person with Windows
has to try it with a debugger [1] (to get the "backtrace" of the
crash). From that output we maybe understand the problem.

Please report this then to
http://trac.osgeo.org/grass/ticket/111

# Spearfish
r.los in=elevation.dem output=tr_vis coordinate=599490,4920855 max_dist=10000
Using maximum distance from the viewing point (meters): 10000.000000
 100%

No problem on Linux, so... (I have no Windows).

I know I must use a debugger, but I do not know how to do it in windows. I have just read the grass debug wiki page, but I can not go forward. I'm a weak user.


Thank you,
