#16065: Stack squeezing during context switches makes for non-determinism in allocations -------------------------------------+------------------------------------- Reporter: sgraf | Owner: (none) Type: task | Status: new Priority: normal | Milestone: ⊥ Component: Runtime System | Version: 8.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #4450, #8861 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): To eliminate determinism, `-V0` by itself is preferable. Stack squeezing by itself is perfectly deterministic, the non-determinism arises when it is done at non-deterministic times, which is a result of time-based context switches. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16065#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
