ntpd then started cleanly. I haven?t tested this across the board yet, though.

I'm not having any issues with ntpd on either 10.2 and 9.3 however on
9.3 the ntp query utilities (ntpdc and ntpq) both crash with sig 6:
...
Oct 26 11:37:48 <ntp.notice> host ntpd[49294]: ntpd 4.2.8p4-a (1):
Starting
...
However 9.3 ntpq and ntpdc:
# ntpq
/usr/src/usr.sbin/ntp/libntp/../../../contrib/ntp/lib/isc/unix/net.c:221: fatal
error: RUNTIME_CHECK(((pthread_once((&once), (initialize_action)) == 0) ? 0
: 34) == 0) failed
Abort trap (core dumped)
# ntpdc
/usr/src/usr.sbin/ntp/libntp/../../../contrib/ntp/lib/isc/unix/net.c:221: fatal

I don't know how much value you can get out of a stripped bt for ntpq:
