 Bug is still present in 8.0.
 
 I have found that system joins multicast group only for the first
 address. For example:
 for address xxxx:xxxx:xxxx:x::110:166 it joins ff02:1::1:ff10:166 as
 shown by netstat -ia (where it listens for example for neighbour
 solicitation messages), but for the second address assigned to the same
 carp4 interface it does not join another group.
 
 It works if I chose the second address with the same last 3 bytes as the
 first address - because it falls to the same multicast group.
