and calculating, in your case, 2^3586885994363551744 is not something your computer is going to like... as it's probably a number which doesn't fit in our universe :)
Hmm, good point. I hadn't thought about the fact that the number of digits in the answer would be rather large...
Still, a segfault might point at a bug, which I unfortunately won't be able to say much about. (Due to lack of knowledge & information.)
My googling suggests that gmp is prone to segfaulting when things get too large for it, so I'll just chalk it up to that. I apologise for thinking this was a bug :-) Cheers, Ganesh
