--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though, the cp_parser_next_token_ends_template_argument_p change can't be
right.
E.g.
struct <int N> A{};
A<1>=2> a;
is not A<1> =2> a;
I bet we can't treat at least >= as terminating template argument, perhaps we
could go back to it if tentative parsing with >= didn't work out.
In any case, not a GCC 12 material as not a regression.
