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

OK, so I suppose the test is a bit extreme, but other than that, I vote for
WONTFIX (or INVALID).

It looks like ~ 256 MB is needed to hold the result of the power
operation being requested (2 ** 0x1fff). This is too much
for this machine.

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.

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 int

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

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].
