#8563: Deriving with PolyKinds broken -------------------------------------+------------------------------------ Reporter: edsko | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by goldfire): Filter out the kind vars in `cls_tys` and `cls_tvs` in `gen_Newtype_binds` in !TcGenDeriv -- I think that should fix it. Let me know if you want me to take a closer look, but it seems like you're on it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8563#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
