Very nice! The fib stack bench basically ends up generating a stack
error, so that's probably the place to start looking. It is intended
to blow up but show roughly how deep it got before the stack error.

Great to hear that the other tests are all working. I'll have to get
back into indy mode and get a recent build made that I can play with!
