Package: iputils-ping
Version: 3:20121221-4
Severity: important
Broadcast ping is broken.
Example where 4 hosts answer, but they are all incorrectly reported
as 172.16.1.17:
$ ping -b 172.16.0.0
WARNING: pinging broadcast address

strace shows that IP is received correctly to 'ping', but stdout write uses
wrong IP:
# strace ping -b 172.16.0.0
