#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): Good catch, but I don't fully understand stack squeezing affects allocation. As far as I'm aware it should just reduce the stack size, not increase it, so it shouldn't require any extra allocation. I'm OK with putting in some fix for this to make the benchmarks stable, but I'd like to completely understand the cause first. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16065#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
