This looks like a problem with gcc under HP-UX, unrelated to gdb or
the PowerPC support. Unfortunately searching for "hpux internal error"
on the gcc mailing list archives reveals a lot of matches, so you will
have to do a bit more searching. You may be able to find a gcc patch
for this specific problem, or you may have more luck with another
release of gcc or with a more recent snapshot - no promises I am
afraid. Good starting points would be:

    http://gcc.gnu.org/
    http://gcc.gnu.org/lists.html
