--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Look into resolve_workqueue. I think there is an alias violation in there.
__gc_stkf is an array of 3 void* and is stored via void*.
(_2-8B)->gcstack is stored off in __gc_stkf inside the array.
And then __gc_stkf is stored off to (_2-8B)->gcstack which is fine.
But then we load from __gc_stkf but via jl_task_t*->prev to get the original
value of (_2-8B)->gcstack. That is definitely an alias violation.
