Hmm... here, after

    rm -rf ~/.emacs.d/eln-cache
    src/emacs -Q --eval '(setq debug-on-error t)' a.org

I get a buffer with no fontification, that claims to be in Org mode but
whose `font-lock-keywords` is just (t nil), which explains the lack
of fontification.

And if I wait long enough for all the org files to be native-compiled,

    src/emacs -Q --eval '(setq debug-on-error t)' a.org

opens up a buffer with the usual fontification.
