But I'm going to guess the issue is similar to #11415. Not an issue with GHC's `deriving Generic`, directly, but with a Generic-based default definition for another class (here Serialize). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10852#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
