[Haskell-beginners] Brainfuck interpreter stack overflow

Hello Edgar

Does the interpreter fail actually fail on particular input rather
than by it running to long?

Tail recursion isn't very important for Haskell as it is a lazy
language, however for any Parsec parser avoiding _left recursion_ is
crucially important as it is a LL recursive descent parser.

Also how are you running the program - GHCi, Hugs? The import
declarations for Parsec suggest that you are using a old version.

Best wishes
