#14880: GHC panic: updateRole -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: 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): Could you maybe provide a quick summary of the exact performance trouble? I'm running some tests as we speak, but it would be easier for me if you could hint at some tests that produce particularly bad behavior, or maybe an example program on which GHC peforms badly after this patch. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14880#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
