#15485: GHC uses 300% CPU when calling into blocking C call -------------------------------------+------------------------------------- Reporter: oconnore | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: 8.6.1 Component: Runtime System | Version: 8.4.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 | (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by osa1): * status: new => infoneeded Comment: oconnore, would it be possible for you to provide a reproducer? I looked at the /r/haskell thread but I still have no idea how to reproduce this. A cabal package would work (please avoid stack if possible, it adds extra friction). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15485#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
