The packet will hit a router which will refuse to forward it.  This is
exactly the same as a node sending a packet with inadequate hop count to
reach the destination.  In both cases the sending node gets back an ICMP
error message (scope exceeded or hop count exceeded).  There is nothing
strange here.
