#10990: Checking whether a default declaration is an instance of a defaultable typeclass is broken -------------------------------------+------------------------------------- Reporter: kanetw | Owner: (none) Type: bug | Status: closed Priority: low | Milestone: Component: Compiler (Type | Version: 7.10.2 checker) | Resolution: fixed | 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: | -------------------------------------+------------------------------------- Changes (by harpocrates): * status: new => closed * resolution: => fixed Comment: Fixed in 9a34bf1985035858ece043bf38b47b6ff4b88efb (I think, although I haven't compiled before and after to check). At the very least, that commit added test cases demonstrating this to be solved. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10990#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
