Currently I have following simple logic

a) src address is the destination address of the packet to which ICMP
 is related.

b) if the address of step (a) is not a valid address on the interface
to which the ICMP is destined, the new valid source address is
selected.

I don't think it is good for *any* RFC to require a stack to send
packets with wrong source address. Thus, if the ICMP draft seems to
require such illegal thing, I think the draft needs revision.
