Angie 1.7.0 dumps core using proxy_http_version 3. If it helps I can compile -O0 - to provide the content of some variables.

Our config is a bit awkward: we want to test http/3 only for certain requests:

    map $http_authorization $upstream_server {
        ''                      http://upstream_http11;
        default                 https://1.2.3.4:5678;
    }
    server {
        location / {
            proxy_pass                      $upstream_server;
            proxy_http_version              1.1;
            if ($http_authorization) {
                proxy_http_version          3;
            }
        }
    }

Can't reproduce on a development machine. This is the line in question:

max_entries = h3scf->max_table_capacity / 32;
