--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
#pragma GCC diagnostic ignored_attributes "n::_a"

There is a check to make sure the attribute isn't named __a__ but the assert
only checks that the attribute starts with _.

Note you can also reproduce the ICE with the following option passed to GCC:
-Wno-attributes=n::_a

Confirmed, not a regression as the warning option is new.
