ntpd multicast TTL

ntpd is a convenient source of multicast packets for testing purposes.
When I add
to my ntp.conf, ntpd sends a multicast packet with TTL 1 every 64
seconds. Just as expected. However, when I explicitly specify the
TTL as in
broadcast 18.104.22.168 ttl 1
it sends packets with TTL 32. Trying a few other numbers confirms
that it multiplies the specified TTL by 32. That is not expected.
(I also don't recall this happening the last time I tried it, but
that may have been years ago.)
Is this simply a bug in ntpd?
