#10642: Coercible regression from 7.10 to HEAD -------------------------------------+------------------------------------- Reporter: darchon | Owner: goldfire Type: bug | Status: closed Priority: highest | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | typecheck/should_compile/T10642 Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by goldfire): `StandaloneDeriving` and normal `deriving` use the same mechanisms. So `StandaloneDeriving` is no more likely to use `coerce` than normal `deriving`. This can most easily be seen when deriving `Show`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10642#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
