Final RHEL6 should be also have fixed this issue because of:

# ping6 -c 1000 -f ::1 -F 12345
Flow labels are not supported.

This isn't related to traceroute issue.

The flowlabel functionality is disabled by default therefore "Flow labels are not supported" message is printed.

Simple enabling doesn't fix it due to problems with headers. I have to investigate it a bit.

During investigation, would be nice if you can also look into the next hop option (source routing), which is not working for IPv6 at all: 

# ping6 -c 1 2001:xxxx:xxxx:65::1 2001:xxxx:xxxx:66:5054:ff:fexx:xxxx
PING ipv6-client-b(ipv6-client-b) 56 data bytes
ping: sendmsg: Invalid argument


IPv4 works (after enabling accept IPv4 source routing on all participating nodes):
# ping 10.0.65.1 ipv4-client-b
PING ipv4-client-b (10.0.66.2) 56(124) bytes of data.
64 bytes from ipv4-client-b (10.0.66.2): icmp_seq=1 ttl=63 time=2.78 ms
LSRR: 	ipv4-router-c-65 (10.0.65.1)
