#13434: hs_try_putmvar003 is timing out / segfaulting -------------------------------------+------------------------------------- Reporter: ezyang | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Runtime System | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: 13722 Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * milestone: => 8.4.1 Comment: It seems that the testcase is getting stuck on `pthread_mutex_destroy` and `pthread_cond_destroy`. Commenting both of these calls in `destroyCallbackQueue` allows the test to run to completion. It seems that the issue is that the `do { ... } while(1)` loop in `callback` never terminates and therefore the mutex is never unlocked. I suspect this fails only now because `glibc` is now more strict about checking that the mutex is not locked before freeing it. Simon, how did you intend for the loop in `callback` to terminate? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13434#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
