#9858: Typeable instance for datatype and its promoted constructor is the same -------------------------------------+------------------------------------- Reporter: dreixel | Owner: dreixel Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by int-e): One way of fixing this would be to prepend a prime (or some other non- capital letter character) to {{{name_fs}}} in {{{TcGenDeriv.gen_Typeable_binds}}} if the given {{{tycon::TyCon}}} is a promoted data constructur. Is this sufficient or are there other ways in which having distinct type constructors with identical {{{tyConName}}} could cause the compiler to go wrong? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9858#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
