#11406: RTS gets stuck in scheduleDetectDeadlock() -------------------------------------+------------------------------------- Reporter: osa1 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | 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 simonmar): This is probably an infinite loop, i.e. a blackhole. The trace you added forces something too early and causes a deadlock. For some reason we don't detect and report blackhole loops as `<<loop>>` in GHC, that is probably worth investigating. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11406#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
