tcIfaceGlobal (local): not found
I have installed Msys2 on Windows. In Msys2 I have installed Emacs, which I start with a custom cmd script with following environment variables set:
SET PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%
set XDG_DATA_DIRS=c:/msys64/mingw64/share
set PKG_CONFIG_PATH=c:/msys64/mingw64/lib/pkgconfig
set INCLUDE=c:/msys64/mingw64/include
The haskell I have is from Full Haskell Platform, https://haskell.org/platform/download/8.2.1/HaskellPlatform-8.2.1-full-x86_64-setup.exe
Then, within Emacs I have started eshell which I used to invoke this command:
cabal install gi-gtk
Which after a while gave me following error.
[91 of 95] Compiling GI.Pango.Objects.Layout ( GI\Pango\Objects\Layout.hs, dist\build\GI\Pango\Objects\Layout.o )
ghc.exe: panic! (the 'impossible' happened)

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.
