| Hi,
|
| while trying to compile the attached file MonadT.hs I got the
| following error:
|
| ghc -fglasgow-exts -c -o MonadT.o MonadT.hs
| ghc-5.02: panic! (the `impossible' happened, GHC version 5.02):
| coreSyn/Subst.lhs:387: Non-exhaustive patterns in
| function zip_ty_env
|
|
| Please report it as a compiler bug to
| glasgow-haskell-bugs at haskell.org, or
| http://sourceforge.net/projects/ghc/.
