Comment (by simonpj):

 Presumably the culprit is the definition of `Proxy#` in `TysPrim`:
 {{{
 proxyPrimTyCon :: TyCon
 proxyPrimTyCon = mkPrimTyCon proxyPrimTyConName binders res_kind
 [Nominal,Nominal]
   where
      -- Kind: forall k. k -> Void#
      binders = mkTemplateTyConBinders [liftedTypeKind] id
      res_kind = unboxedTupleKind []
 }}}
 Are you happy to dig?
