#12949: Pattern coverage mistake -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 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: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Note that everything works as expected if I pass in the `Boolly` values explicitly. Perhaps the pattern coverage checker is confusing `knownBool` called at different types? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12949#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
