Summary:                    93668 introduces segfault into chan_iax
Description: 
...which is not fixed by the next commit too..
I'm making _outbound_ call to one of my peers which does not have
"host=dynamic" but rather has IP address. Then: 
1. realtime_peer function receives NULL sin
2. var = ast_load_realtime("iaxpeers", "name", peername, "host",
"dynamic", NULL);  fails because my peer is not dynamic
3. Evntually /* Last ditch effort */ is executed and where the loop does
IP address comparison (memcmp(&sin2, &sin->sin_a
ddr, sizeof(sin2)) != 0) everything crashes obviously
