That is really some regression bug :-)
Anyone with a more recent version thatn 7.4.1?
I don't even have a problem with 7.4.1: $ for ghc in $GHCS; do echo $ghc; time ./hskahan-$ghc > /dev/null; done; 7.0.4 real 0m0.217s user 0m0.214s sys 0m0.002s 7.2.1 real 0m0.197s user 0m0.194s sys 0m0.002s 7.2.2 real 0m0.187s user 0m0.187s sys 0m0.000s 7.4.1 real 0m0.253s user 0m0.249s sys 0m0.003s 7.4.2 real 0m0.250s user 0m0.247s sys 0m0.002s 7.6.1 real 0m0.224s user 0m0.221s sys 0m0.002s $ time ./ckahan > /dev/null real 0m0.102s user 0m0.079s sys 0m0.022s We have an unpleasant regression in comparison to 7.2.* and the 7.4.* were slower than 7.6.1 is, but it's all okay here (not that it wouldn't be nice to have it faster still). Are you on a 32-bit system?
