Comment (by ezyang):

 I've reduced the test case example. It appears to be related to the
 Generic binary implementation:

 {{{
 {-# LANGUAGE DeriveDataTypeable #-}
 {-# LANGUAGE DeriveGeneric #-}

 module Distribution.Version  where

 import Data.Binary      ( Binary(..) )
 import Data.Data        ( Data )
 import Data.Typeable    ( Typeable )
 import GHC.Generics     ( Generic )

 data T = A
        | B
        | C T
        | D T T
        | E T T
   deriving (Data, Generic, Typeable)

 instance Binary T
 }}}
