This seems to have fixed it, from the cereal 0.5.2.0 release notes:
Split the GSerialize class in two, to deal with a GHC bug (thanks Austin Seipp!)
The GHC bug they refer to is #5642, and it is still open. Thanks again for reporting. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12148#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
