Hi,
what version of ghc did you compile your program with? Based on your
stack size setting, I'm guessing ghc-2.10 :-) Since then, List.sort
has been speeded up quite a bit (i.e., we're not using the sample
implementation in the Prelude any longer), and I'm unable to reproduce
your problem with ghc-3.02 (or ghc-3.03).
If you don't want to upgrade ghc right now, I can compile up your code
on a local linux box, if you like.
