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).
