If you compile with > -O2 rather than -O3 the false alarms (and one true alarm :-) should go away. Thanks. I'm not yet sure which part(s) of the changeset directly shut up the "-Walloc-size-larger-than=N" warnings. Is that the part that adds the calls to 'assume'? If so, we already call eassume in many places; it won't be a problem to add a few more, and fix the warnings on the emacs-27 branch. And what about a similar warning I reported in bug#39857?
