Core dumps in HP's compiler should be filed with HP as a compiler bug.
They are surely not our problem.
My own experience on HPUX 10.20 is that HP's cc tends to dump core when
given both +O2 and -g. Evidently it's still not fixed as of 11.0.
I'd suggest backing off the optimization level in CFLAGS, or using gcc.
