ghc: panic! (the 'impossible' happened)

Hello,

I get the following output in ghci ordering me to report this bug:

Prelude> :load keltis_typedefs.hs
[1 of 1] Compiling Main             ( keltis_typedefs.hs, interpreted )
ghc: panic! (the 'impossible' happened)
  (GHC version 7.4.1 for x86_64-unknown-linux):
	nameModule eq{tv a9U}

I'll attach the file I was trying to load (don't laugh, I was just experimenting with Haskell).

Best regards & thank you,

Tobias
