[GHC] #9148: tryReadMVar locks up the process with +RTS -N2 or greater
#9148: tryReadMVar locks up the process with +RTS -N2 or greater ------------------------------------+------------------------------------- Reporter: simonmar | Owner: simonmar Type: bug | Status: new Priority: highest | Milestone: 7.8.3 Component: Runtime System | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: Runtime crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- The new `tryReadMVar` is missing an `unlockClosure` call, which causes the whole process to hang when used with +RTS -N2 or greater. I'll push the fix shortly. We should treat this as a blocker for 7.8.3. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9148 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

That's what I get for cargo-culting the test-case definitions and forgetting to have them run multithreaded as well. Are you going to push updates to the test suite as well? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9148#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
