#13099: recompilation can fail to recheck type family instance consistency -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: rwbarton Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by rwbarton): I'm not sure whether you meant LHS rather than RHS; in any case the consistency check depends on both.
As always with these sorts of bugs, a failing test case helps a lot!
OK, I'll add a failing test case and then probably release the ticket. (But not immediately.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13099#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
