I wasn't sure if that field (ifa_p->ifa_addr) could be NULL, but the
output of "ip addr list" made me suspicious! For "tun0" the result was:

5: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc
pfifo_fast state UNKNOWN qlen 100
    link/none 
    inet 192.168.XXX.XXX peer 192.168.XXX.XXX/32 scope global tun0

Because of "link/none" I started to dig a bit deeper.

The patch works on my system.
