--- Comment #4 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
OK.  I'm going to revert the original patch until I can reproduce this and
start looking at it.  There's clearly something different about the aarch64
port and varargs that doesn't like this approach.  None of these things
reproduce on Power systems.
