1981	panic when compiling record implementation using type families	jeltsch	igloo	"Attached is a current snapshot of the grapefruit-records package.  Compilation of this package fails with this error message:
{{{
ghc-6.8.2: panic! (the 'impossible' happened)
  (GHC version 6.8.2 for i386-unknown-linux):
        mkStgAlts grapefruit-records-0.0.0.0:Data.Record.Complete{tc r1KI}

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
}}}

Sorry that again I don’t provide a smaller test case.  At the moment I have so little time to actually work on Grapefruit and the related research that I really don’t want to spend much time for searching smaller test cases. :-( "	merge	closed	normal		Compiler	6.8.2	fixed			Linux	x86		Unknown	T1981
