Ouch, I had completely misread the question.  Voracious consumption
of memory is also a property of GCC for C. Gcc hits the ceiling
(or floor) for even a short C program:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56344

Another way to ask, then, might be, if there is a GNAT
executable that will itself use a PAE kernel's extended addressing?

If doubling memory only defers the issue, maybe that's something
to ask on the GCC list?
