#15398: GADT deriving Ord generates inaccessible code in a pattern with constructor. ---------------------------------+-------------------------------------- Reporter: philderbeast | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by RyanGlScott): I'm not sure what exactly the bug is here. The generated code genuinely has inaccessible cases, and since GHC 8.6+, this is a warning instead of an error, so you can now actually use this code. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15398#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
