--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Right away I can say it is not phiopt that is causing the issue:
That is:
doing `__attribute__((optimize(3, "no-ssa-phiopt")))` (instead of just 3) still
fails.

Turning off SRA allows it to work but I suspect SRA is just exposing it.
