Nevertheless, I wonder if there might be an alloca-type memory leak
going on here.  I see that Paul added some 'alloca (0);' lines in
read.c.  You could try 3.81rc1, edit function.c,  and add 'alloca
(0);' just before the 'free (result);' line in func_foreach.  That's
probably overkill, as well as a serious slowdown, but it could give
Paul a better idea about how to workaround the problem.
