#15482: the_gc_thread variable from GC.c is not aligned to 64 -------------------------------------+------------------------------------- Reporter: arrowd | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | 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): Phab:D5052 Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * status: closed => new * differential: => Phab:D5052 * resolution: fixed => Comment: Ahh, I see the issue now. We explicitly claim that `gen_workspace` should be 64-byte aligned. I was previously under the mistaken impression that the problem was merely that `the_gc_thread`, a `StgWord8[]`, wasn't aligned to 8-bytes as `gc_thread` would require. I pushed a new fix as Phab:D5052 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15482#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
