#13330: forkIO has inconsistent behavior under optimization -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: dfeuer Type: bug | Status: patch 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): Phab:D3189 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): In a conversation on Monday I think we agreed: * We should try changing `catch#` to be lazy (but still with a `C1(d)` usage) and see what perf effect, if any, that has. * Neil Mitchell was part of the conversation on #11555; see comment:11 there. So let's check with him too. I think David is leading on this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13330#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
