Comment:

 A quick calculation on a napkin indicates computational region causing
 memory demand larger than Windows limits. There's nothing we can do except
 rewrite of all signature generation code to not keep all data in memory
 (any volunteers?). As this option is not requested in this ticket, I'm
 closing it.

 Original reporter - reduce size of your computational region and try
 again. Second option - compile a 64bit version of GRASS GIS and run it on
 a 64bit Windows. More information on memory limits on Windows:
