#16289: GHC thinks pattern match is exhaustive -------------------------------------+------------------------------------- Reporter: dnspies | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: | PatternMatchWarnings 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 harpocrates): This looks suspiciously like https://ghc.haskell.org/trac/ghc/ticket/15713 (that's about overloaded strings, but otherwise pretty much the same situation). There's something fishy about exhaustiveness checking on overloaded literals in general. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16289#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
