#14498: GHC internal error: "not in scope during TC but it passed the renamer" -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.2.1 checker) | Keywords: Resolution: | PatternSynonyms Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: #14288 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Ah, indeed comment:6 of #14288 concerns exactly this point. Short term: GHC should not crash. Maybe it should just reject the program. Slightly longer term: we need to decide if we want to adopt the proposal in commment:15 of #14288. Would this be worth a short GHC proposal? It's certainly a change in the surface language. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14498#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
