#14237: -Wredundant-constraints incorrectly treats all type equality constraints as redundant -------------------------------------+------------------------------------- Reporter: lexi.lambda | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: #12700 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * related: => #12700 Comment: Yes, this is a known pain point of `-Wredundant-constraints`. See also the very similar ticket #12700. (Among other reasons, this is why `-Wredundant-constraints` is no longer a part of `-Wall`.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14237#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
