#8402: throwTo segfaults under -prof -threaded -with-rtsopts=N2 ----------------------------------+---------------------------------- Reporter: akio | Owner: Type: bug | Status: patch Priority: highest | Milestone: 7.8.1 Component: Profiling | Version: 7.7 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ----------------------------------+---------------------------------- Comment (by kazu-yamamoto): I'm trying to profile my web server with GHC head (+RTS -Nx -p). Without ezyang's patch, it causes a segfault when I type C-c to stop the server. With GHC 7.6.3, C-c stops the server and generates a profile file. With ezyang's patch, this segfault disappeared. However, all counters are displayed 0: {{{ individual inherited COST CENTRE MODULE no. entries %time %alloc %time %alloc MAIN MAIN 347 0 100.0 100.0 100.0 100.0 CAF Main 693 0 0.0 0.0 0.0 0.0 CAF Server 692 0 0.0 0.0 0.0 0.0 CAF WaiApp 690 0 0.0 0.0 0.0 0.0 CAF Program.Mighty.Config 688 0 0.0 0.0 0.0 0.0 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8402#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
