#12521: Thread blocked indefinitely in an MVar operation -------------------------------------+------------------------------------- Reporter: SwiftsNamesake | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 | (amd64) Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by SwiftsNamesake): * I'm using Windows 10. * chcp is a windows command which changes the active code page I was trying to print Unicode characters. I launched the Windows console (cmd), started GHCi, ran that putStrLn- snippet and (obviously) got an exception. I don't remember exactly but I must've terminated GHCi (:q), changed the code page and then restarted GHCi to try again (in quick succesion). I remember the commands from cmd and GHCi being 'interleaved' (ie. things I started typing into the CMD appeared inside GHCi later on). It's possible that it's really CMD which is at fault but I decided to report it anyway since I was asked to. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12521#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
