#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): Phab:D3189 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Yes, you could have a special rule for `catch` as we do for `case` I suppose. But we can't express it in the demand signature for `catch`; demand signatures aren't expressive enough. But before cluttering up the demand analyser with special cases, I'd like to see evidence that it made a material difference. I doubt it would. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13330#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
