Most interesting is that while many notice `-kc1M` cure the problem they still insist it runs much slower than Ocaml version. But it is *NOT*!
Interesting to hear about this difference between platforms. On Linux (and apparently OS X) it just eats all memory and does not finish. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7850#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
