--- Comment #34 from Richard Biener <rguenth at gcc dot gnu.org> ---
The .DEFERRED_INIT RTL expansion creates aligned stores and the decl is
appropriately aligned, even with -fno-tree-vectorize, by pass_adjust_alignment.
Disabling that pass avoids the issue.
I think that we need .DEFERRED_INIT to trigger this is futile, we do
have RTL assigned to 'k' with 128bit alignment but that is appearantly
not correct.
