I've found an older ticket which might be the reason: https://ghc.haskell.org/trac/ghc/ticket/10301

Hasn't landed in GHC 8.0.2 yet so can't tell if this fixes this instance as well.

Update: I've tested it with GHC HEAD and it works there. So it's just a matter of waiting until the fix makes it into stable.

Works with 8.0.2 and HEAD for me.

I've just confirmed this again on my Notebook [W10 64Bit (Build 14393) with GHC-8.0.2] What version of windows are you running?

I don't have GHC-Head configured here so can't test that now, but I assume that would work.

I'm also using 8.0.2 and getting this panic:

ghc.EXE: panic! (the 'impossible' happened)
  (GHC version 8.0.2 for x86_64-unknown-mingw32):
        Static flags have not been initialised!
