--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This regtested/bootstrapped patch fixes it, but I'm not fully confident it's
the Right Place.  The problem is that constructor_designated wasn't set
properly when entering pop_init_level from c_parser_braced_init, since
push_init_level called earlier set it to 0.
