Comment(by jtb):

 Thank you for your quick response! Great that it is already fixed in HEAD.

 And as you posted the error messages, I was actually able to correct my
 code :).

 but not in the 7.4 branch. I'm not closing since I'm not sure which commit

 actually fix this and if it is easy to merge it into 7.4 branch (from

 looking at the logs it might have been

 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
