GHC 8.2.2 crashes while building the haskell-gi sample code in a new project created with stack (see the attached project).

Steps to repro:

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

New description: 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.
