#14880: GHC panic: updateRole -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: 8.8.1 Component: Compiler (Type | Version: 8.2.2 checker) | Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: #15076 | Differential Rev(s): Phab:D4769 Wiki Page: | -------------------------------------+------------------------------------- Comment (by tdammers): Yes, will do. Rebasing the whole thing on `HEAD` is going to be a bit hairy, but no show stopper. One thing I find remarkable is that `Set` doesn't do the existence test, but I guess that's just a matter of prioritizing CPU over RAM that turns out in our disadvantage in this specific case. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14880#comment:98 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
