I forgot to mention that the command works perfectly fine with a
smaller region (971 r x 1746 c) it's only on the larger region that it
starts having problems. Markus, perhaps you could try running the
command on a map closer to the one I was running it on (14342 rows,
14501 cols.) to see if you get errors.
I tried the gdb thing mentioned by Hamish but I got an error "Error:
dll starting at 0x78d41000 not found." Maybe it doesn't work well in
cygwin.
Perhaps instead the contents of the stackdump file could help...

I guess I'll try winGrass now, let me know if you can think of
anything else that could help me.

I have tried your command slightly modified in Spearfish on Linux, no
problems.
Here are the latest changes:
http://freegis.org/cgi-bin/viewcvs.cgi/grass6/raster/r.cost/?sortby=date#dirlist
Probably the Cygwin binaries are older (the web site where you got them
should
indicate the date).
Maybe give the new (experimental) winGRASS a try?
