#15349: fixST is a bit wrong -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: dfeuer Type: bug | Status: merge Priority: normal | Milestone: 8.6.1 Component: Core Libraries | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4948 Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Note: the crazy implementation above never actually needs to `takeMVar`; `readMVar` should be sufficient. So `IVar`s would be sufficient. But to get close to something practical, we need to avoid `forkIO`. Maybe I can do that; I'm not sure. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15349#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
