#11760: runST with lazy blackholing breaks referential transparency -------------------------------------+------------------------------------- Reporter: Yuras | Owner: dfeuer Type: bug | Status: patch Priority: highest | Milestone: 8.2.1 Component: Core Libraries | Version: 7.10.3 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:D3038 Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): We still need a more reliable test case. I managed to make a variation of this one fail moderately reliably using lots more threads, but I have an idea for another approach that's probably cheaper and more reliable; I'll try to get to that shortly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11760#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
