The suggested patch is going to fix only one place, however the same
stack overflow may be reached using several other places which use
do_alloca(). I'll try to think about general solution.

Yes, an smaller limit like 1024 looks OK and is still high enough to
avoid annoying insane coders ;-)

That would already allocate 64kb on the stack, I doubt that will work
on all systems. I would suggest a somewhat smaller limit, say 1024?
