The situation still exists. See below:

v6host2:~# traceroute -q 10 -w 10 v6test1
traceroute to v6test1 (5f06:7b00:8c70:1300:0:80:c81a:9c3),
30 hops max, 60 byte packets
1 v6test1 (5f06:7b00:8c70:1300:0:80:c81a:9c3) 1.914 ms *
2.079 ms * 1.662 ms * 3.191 ms * 1.672 ms *

By the way, if I specify the packet size larger than
(approx.) 1536 bytes there will be a kernel fatal error. :-(
