 Hello, I was playing with unboxed types and this happened:

 [2 of 2] Compiling Data.Unbox       ( Data/Unbox.hs, .stack-
 work/dist/x86_64-linux/Cabal-1.24.0.0/build/Data/Unbox.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 8.0.1 for x86_64-unknown-linux):
         pprIfaceCo

 I will attach the relevant file.
