Comment (by Iceland_jack):

 I get a Googlelocatably-similar error message with

 {{{#!hs
 {-# LANGUAGE PolyKinds, TypeInType #-}

 import GHC.Exts

 data A :: TYPE rep -> Constraint
 }}}

 using GHC version 8.0.2

 {{{
 *** Exception: expectJust zonkTcTyVarToVar
 CallStack (from HasCallStack):
   error, called at compiler\utils\Maybes.hs:48:27 in ghc:Maybes
 }}}

 I can't remember if this has been reported already.
