I have been using this patch locally on one machine, and have not noticed any ill effects. And on another machine, where I do not have the patch applied, I once again ran into the problem with gnulib's recent rename of allocsa->malloca, which had no problems on the first machine. Any chance you can revive and include this patch? - -- Don't work too hard, make some time for fun as well!
