Alas yes, it tickles a compiler bug in gcc 2.95.2.  Replacement below.

Yes turning down the optimizations often helps.

I think we've tested on such systems, so I'm not sure what would be
going wrong.  Please provide the whole output from "make check", or at
least the list of which tests come out as "PASS" and "FAIL".  Pick a
simple one if you like to try to trace the problem.

If you just want to get something working, a generic C build might
give more joy,

    ./configure --target=none-hp-hpux10.20 CFLAGS="-g -DNO_ASM"

or similar.
