#16008: GHC HEAD type family regression involving invisible arguments -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: patch Priority: highest | Milestone: 8.8.1 Component: Compiler (Type | Version: 8.7 checker) | Keywords: TypeFamilies, Resolution: | TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D5435 Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: new => patch * differential: => Phab:D5435 Comment: Oh wow, I was not aware of `checkConsistencyConstraints`! That's a much cleaner solution, and better yet, it doesn't cause any existing tests to change their expected output. I've submitted a patch as Phab:D5435. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16008#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
