internal compiler error: the `impossible' happened
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
glasgow-haskell-bugs@haskell.org,
or http://sourceforge.net/projects/ghc/.
I spent some time stripping the file to only several
lines :)
Best regards
