#14004: G -------------------------------------+------------------------------------- Reporter: zaoqi | Owner: (none) Type: feature request | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AntC): The error I see is that the `{-# OVERLAPPING #-}` pragma is on the wrong instance. The `GEq a a` instance should have `{-# OVERLAPPABLE #-}`; the `GEq a b` should have `{-# OVERLAPPING #-}`. The instance for `Dyn` doesn't mention `GEq`. I agree with Ben, Ryan: I see no bug. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14004#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
