#13330: forkIO has inconsistent behavior under optimization -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Core Libraries | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): To be specific, the expected behavior of the test is for the `undefined` exception to be reported and then for the program to run for a second and then exit. This is the behavior without optimizations, and also the behavior under GHC 7.10 and earlier regardless of optimization level. Basically, the same situation as with `catch` in #11555. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13330#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
