The program seems to take around 6 seconds on my linux-box, while the c version
goes for 0.06 sekcond.
That is really some regression bug :-)
Anyone with a more recent version thatn 7.4.1?

That's really an argument for upgrading to 7.4.2 :-)
Another reason for doing things with haskell is this mailing list.
Thanks!

Are you on a 32-bit system?

I'd also like to point out that I've removed lots of bang patterns
that weren't needed. This program runs fine without any bang

On my (64-bit) machine the Haskell and C versions are on par.
Yes, but the result is very different.

On my box, the Haskell is even faster then, but, as said, the result is
incorrect
