In below Eric Schrock's blog, it said it was difficult to get them, since the arguments may or may not be pushed on the stack, or they could be lost completely. http://blogs.sun.com/eschrock/entry/debugging_on_amd64_part_two It seems to be true in the earlier Nevada build, but in recent Neveda build, ::findstack could return the input arguments very well.
