That's easily fixable by adjusting MAX_ALLOCA down to a bit less than 4
KiB (which is what Gnulib code does) or by arranging for more guard
pages than usual (more hassle, but eminently doable on most platforms).
Emacs already has a stack-overflow prevention mechanism, right? And
we're talking about what to do when the user deliberately disables it?
So the simplest answer is "don't do that".
