 While building one of my projects, GHC crashes with the following message:
 {{{
 ghc: panic! (the 'impossible' happened)
   (GHC version 8.0.1 for x86_64-unknown-linux):
         find_tycon
   Block
   []

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

 The project I'm trying to build can be found at
 https://github.com/nek0/eidolon.
 The file it crashes at is called `Foundation.hs`
