#10199: Sending SIGINT to a program that uses forkOS may crash with various errors -------------------------------------+------------------------------------- Reporter: adeon | Owner: simonmar Type: bug | Status: new Priority: low | Milestone: Component: Runtime System | Version: 7.10.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Runtime crash | (amd64) Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonmar): Yes, what happens here is that the RTS shuts down while one of the forkOS calls is just about to call back into Haskell to create the bound thread. The effect is similar to calling a foreign exported function before calling `hs_init()` - that's where the `newBoundTask` message comes from. Depending on the timing, we might have got past the `newBoundTask` check when the RTS shuts down. We should close that race condition. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10199#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
