Please report it as a compiler bug to glasgow-haskell-bugs at haskell.org,
or http://sourceforge.net/projects/ghc/.

Where test.hs is:
-----------8<------------------------------------------------------------
module Test where
import Language.Haskell.THSyntax
data T = T { a, b :: Int }
f x = x * x

With the Debian unstable (6.2.1-2) Version of GHC.
