Comment (by lippling):

 I seem to have a similar bug (with 8.0.2) in a Yesod app (the app compiles
 fine with 7.10.3):

 {{{#!hs
 [61 of 61] Compiling Application      ( Application.hs, .stack-
 work/dist/x86_64-osx/Cabal-1.24.2.0/build/Application.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 8.0.2 for x86_64-apple-darwin):
