Bang in front of type name crashes GHC

When adding a bang to a type constructor applied to a type, I forgot to surround it with parenthesis:

module Test where

import Data.IntMap

data T = C { f :: !IntMap Int }

leading to the following crash:

[1 of 1] Compiling Test             ( Control/Distributed/Hayride/Test.hs, interpreted )
ghc: panic! (the 'impossible' happened)
  (GHC version 7.6.0.20120810 for x86_64-unknown-linux):
        tc_hs_type: bang

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
