I have this little demo which I use for sixth formers which includes calculating in fairly rapid order the sum of the digits of the 10^9th Fibonacci number. (I haven't got enough physical memory to do the same for the 10^10th number without thrashing...) It fell over on a flashy new macbook I was going to use for the presentation the other day; indeed I found I couldn't even calculate the sum of the digits of the 10^6th number.
For the record this was reported as GHC #12954. Cheers, - Ben
