[Haskell-beginners] exceptions and stacks

[Emmanuel Touzery]

OK apparently i just needed to build normally then again with:

 ghc -prof -auto-all -osuf prof *.hs

Well the instructions were clear but it was after the big fight with cabal.

Well now the executable is 47Mb compared to 23Mb before, but if I'll get
the stack it's worth it. It's running now, it takes a while before it hits
the crash.
