(In reply to Conrad Meyer from comment #8)

RFC 4861 say: 
--snip--
   If the source address of the packet prompting the solicitation is the 
   same as one of the addresses assigned to the outgoing interface, that 
   address SHOULD be placed in the IP Source Address of the outgoing 
   solicitation.  Otherwise, any one of the addresses assigned to the 
   interface should be used.   
--snip--

So it IS permissible for another address to appear here. RFC 5942 that updates
RFC 4861 seems to not change this.

This is probably why it works on Linux, windows, DragonflyBSD etc. I guess they
have seen this as the statement is quite clear.
