--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think the issue was probably latent and the function assumes that bitfield
accesses are rejected earlier but now are no longer(?).  vect_analyze_data_refs
is usually responsible for that, eventually we also rely on data-ref analysis
itself to reject bitfield accesses.
