(This is on sparc-solaris) # /usr/local/pub-bkb/ghc/ghc-latest/bin/ghc --make resources/GUIValue.hs resources/Colour.hs -fglasgow-exts ghc-5.02.3: chasing modules from: resources/GUIValue.hs,resources/Colour.hs Compiling GUIValue ( resources/GUIValue.hs, resources/GUIValue.o ) Compiling Colour ( resources/Colour.hs, resources/Colour.o ) ghc-5.02.3: panic! (the `impossible' happened, GHC version 5.02.3): Maybe.fromJust: Nothing
Please report it as a compiler bug to [EMAIL PROTECTED], or http://sourceforge.net/projects/ghc/. Is there a workaround, or am I going to have to go back to ghc5.02.2? Personally I suspect multi-parameter type-classes
