#7970: Thread GC frees roots before thread actually finishes ---------------------------------+------------------------------------------ Reporter: joeyadams | Owner: simonmar Type: bug | Status: new Priority: high | Milestone: 7.8.1 Component: Runtime System | Version: 7.6.3 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: Runtime crash Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: 7170 | ---------------------------------+------------------------------------------ Changes (by simonmar): * owner: => simonmar * difficulty: => Unknown * priority: normal => high * milestone: => 7.8.1 Comment: This is technically not a bug - the thread is unreachable when it is deadlocked, and so is the weak pointer. However, we have had a feature request in the past to change this behaviour, and I can see that in this case it is less than useful. I'll look into reversing the order so that we establish the reachability of threads before weak pointers. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7970#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
