Is this the bug where a prefix for interface Y is send out on interface X?

I'm not sure what's happening here.  I added a debug message which 
verifies the interface before sending a packet and it appears to be 
working correctly, but isn't.  I haven't been able to figure out if this 
is some kind of bug with sendmsg or if radvd is just using it incorrectly.

I have noticed that the bug is present in older versions of radvd.  Does 
anybody care to test this on older versions of Linux or maybe on BSD to 
see if the bug is there too?
