Dear Haskellers, I've got the following error message during compilation of the attached Signal.hs file with ghc 6.4 and 6.5. ghc -c Signal.hs ghc-6.4: panic! (the `impossible' happened, GHC version 6.4): types/Type.lhs:(1107,0)-(1108,77): Non-exhaustive patterns in function zip_ty_env Please report it as a compiler bug to firstname.lastname@example.org, or http://sourceforge.net/projects/ghc/. I spent some time stripping the file to only several lines :) Best regards
