--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
IPA - gimple "phase ordering" issue. Alternatively when 'b' is discovered
read-only its analysis would need to consider the initializer propagated and
thus eventually not address-taken to make 'a' readonly as well ... (or apply
modref to tell 'a' is not written to?)
