#12117: Thread by forkIO freezes (while read :: Int if error appears) when compiled with -threaded option -------------------------------------+------------------------------------- Reporter: wapxmas | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.10.3 Resolution: | Keywords: -threaded, | freeze Operating System: Windows | Architecture: x86_64 | (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by thomie): * cc: Phyx-, simonmar (added) * component: Compiler => Runtime System Comment: Sees like a Windows-only problem. Reproducible with GHC HEAD (9c3e55bd029447d9c2cac1c9ca1607a8a803cd79).
if build as "ghc concbug.hs" - program work as expected
I'm not sure. For me, on Windows, it doesn't print the "seconds is up! BING!" line, until I enter some non-number string. It also never prints "Prelude.read: no parse", as it does on Linux. But the program doesn't freeze, as it does with `-threaded`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12117#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
