GNU MP: Cannot reallocate memory (old_size=4 new_size=268435472)

this looks like a GMP bug, not a GCC bug [GCC doesn't even use GMP, only
MPFR which is used does].

What's your GMP version?  Try updating to the latest-and-greatest here.

You might also want to build GMP and MPFR with internal checking enabled
(--enable-assert, I think). Doesn't this one appear on hpux11?

To go further, here's the information I think we need: What versions of GMP and
MPFR are you using? Do they pass checking (make check in their respective build
directories)? What happens if you build them with internal checking (asserts)
turned on?

They are the latest: gmp-4.2.2 and mpfr-2.3.1.  I'll rebuild and test
with asserts.

The same errors appear with gmp-4.2.4 and mpfr-2.3.2 built with
--enable-assert.
All tests pass with make check for both.

It looks like ~ 256 MB is needed to hold the result of the power

268 MB for one number is a bit much!  However, I think this is a gmp issue.
