--- Comment #2 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Confirmed, but this is quite odd.  A compiler configured for debug works fine,
but a compiler configured for bootstrap errors as described.  The test case is
fine as written since we are just compiling code for a power9 target, not
executing it.  CCing others for suggestions on what would cause the P9 target
flags to go belly up when bootstrapped but not otherwise.
