#15136: High CPU when asynchronous exception and unblocking retry on TVar raced -------------------------------------+------------------------------------- Reporter: nshimaza | Owner: osa1 Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Runtime System | Version: 8.4.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by osa1): * owner: (none) => osa1 Comment: I'll try implementing comment:5 see how it goes. This code path is not tested enough so I'll also try to port some of concurrency tests that use MVar and async exceptions (exercising `raiseAsync()`) to STM. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15136#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
