panic when compiling record implementation using type families
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. :-(
