I was going to file exactly the same RFE for dynamic_cast and final types
(preferably it should also work if 'final' is only detected by LTO, but that
shouldn't block an easier front-end patch), so confirmed.

I have something like this:
│ 2680 future<> system_keyspace_make(distributed<replica::database>&
dist_db, distributed<service::storage_service>& dist_ss,
sharded<gms::gossiper>& dist_gossiper, db::config& cfg) { │
│ 2681 register_virtual_tables(dist_db, dist_ss, dist_gossiper, cfg);
...
│
│ 2687 for (auto&& table : system_keyspace::all_tables(db_config)) {
...
│ 2695 co_await db.create_keyspace(ksm,
dist_ss.local().get_erm_factory(), true,
replica::database::system_keyspace::yes);
And I see a crash as if the std::vector returned by all_tables() is not
persisted. This worked in previous gcc versions and works in clang.
I don't now what the standard says, but it really should persist temporaries in
range for that contains a suspension point, or a lot of buggy code will be
written.

Oops, last comment intended for a separate bug. Curse the bug list thing.

Avi, in the BZ Preferences you can set "After changing a bug" to "Show the
updated bug" instead of jumping to the next one in the list.

I already owe you many beers, but this one is special.
