#14626: No need to enter a scrutinised value -------------------------------------+------------------------------------- Reporter: heisenbug | Owner: heisenbug Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: performance Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #13861 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by heisenbug): Hmm, I made a run with traces about which `Id`s the condition holds for: https://circleci.com/api/v1.1/project/github/ghc/ghc/951/output/108/0?file=t... you have to `grep getCallMethod` to find them. If I treat those values as tagged, and simply return them, the `ghc-stage2` crashes. :-( So something is definitely fishy here. For completeness, this is what I changed: https://github.com/ghc/ghc/compare/92f6a671a6a8...8f627c9f25b6 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14626#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
