 Hi,

 I checked the command on WinGRASS-6.3.0RC6 (WinXP). It's the same for me.
 BTW, the error seems to be not related to WinGRASS, but to the map in use
 or to the module as cross-platform error (maybe related to the dimension
 of data to be processed?). For example, I launched the command on another
 raster dem map (with a resolution of 20m) with dist set to 3000, and it
 works fine, while it fails with 3001!
 Could someone test it also on linux or mac?

 Thank you

 Marco
