 GHC 8.2.2 crashes while building the haskell-gi sample code in a new
 project created with stack:

     ghc: panic! (the 'impossible' happened)
       (GHC version 8.2.2 for x86_64-unknown-linux):
         tcIfaceGlobal (local): not found
       You are in a maze of twisty little passages, all alike.
       While forcing the thunk for TyThing Layout
       which was lazily initialized by initIfaceCheck typecheckLoop,
       I tried to tie the knot, but I couldn't find Layout
       in the current type environment.
       If you are developing GHC, please read Note [Tying the knot]
       and Note [Type-checking inside the knot].
       Consider rebuilding GHC with profiling for a better stack trace.
       Contents of current type environment: []
       Call stack:
           CallStack (from HasCallStack):
             prettyCurrentCallStack, called at
 compiler/utils/Outputable.hs:1133:58 in ghc:Outputable
             callStackDoc, called at compiler/utils/Outputable.hs:1137:37
 in ghc:Outputable
             pprPanic, called at compiler/iface/TcIface.hs:1696:23 in
 ghc:TcIface

 Steps to repro:

 1. Download the attached project
 2. Unarchive
 3. run `stack build` in the project folder.
