The failure can be fixed by adding the 'template' keyword:

    for (const auto &i: p)// ERROR
        i.second.template get_value<int>();
                         ^^^^^^^^^

Jason, is G++ correct to require that there?

If so, should it also require it on the previous loop?

    for (const C::value_type &i: p)// OK
        i.second.template get_value<int>();
                         ^^^^^^^^^

i.e. is the real bug that we accept the first loop, not that we reject the
second?
