That is a confusing error message caused by a bug in GHC that was just reported a few days ago. The GHC team is fixing it.

putStrLn $ show result

<<loop>>

That is the *real* error message. It means that where you define result, you refer to result also on the right-hand side in a way that is an endless loop instead of well-behaved recursion. We would have to see more of your code to be able to say much more. Regards, Yitz
