I haven't done any MS development in over a decade (happily), so  
maybe I'm just missing something. This is how I get a BT on OSX/ 
FreeBSD when I'm debugging my extensions:

% gdb ruby
 > r my_script.rb my_args
.... go boom
 > bt
... backtrace with hopefully useful information

Can you not do that from the MS debugger???
