--- Comment #2 from Sam James <sjames at gcc dot gnu.org> ---
The thinking was that the TBAA info is more likely to explode with LTO, but
you're right that it's not clear cut, and I don't think I've ever seen it fire
on GCC itself. The warning is pretty limited anyway so let's not worry about
that one.
