#4162: GHC API messes up signal handlers -------------------------------------+------------------------------------- Reporter: jcpetruzza | Owner: Type: bug | Status: patch Priority: low | Milestone: Component: GHC API | Version: 6.12.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): phab:D2633 Wiki Page: | -------------------------------------+------------------------------------- Changes (by hsyl20): * differential: D2633 => phab:D2633 Comment: Note that my patch in comment:14 doesn't make `runGhc` thread-safe if several `runGhc` are executed concurrently. E.g., in the following case: {{{#!haskell runGhc (1) install handlers runGhc (2) install handlers runGhc (1) uninstall handlers runGhc (2) uninstall handlers -- reinstall handlers installed by `runGhc (1)` -- overwriting initial handlers }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4162#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
