  Installed: 1.4.15-5ubuntu3.2

check_ping -6 fails to parse output from ping6 to unreachable hosts in two ways, both fixed in 1.4.16
Relevant Debian and upstreams bugs are:

http://sourceforge.net/p/nagiosplug/bugs/392/
and
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=662638

Output from 1.4.15-5ubuntu3.2:
# /usr/lib/nagios/plugins/check_ping -H 2001:6b0:e:2018::9999 -w 5000,100% -c 5000,100% -p 1 -v -v -v -6

Output of same version, but fix from debian bug 514588 applied:
# ./check_ping_514588 -H 2001:6b0:e:2018::9999 -w 5000,100% -c 5000,100% -p 1 -v -v -v -6

Finally, with fixes from both 514588 and 662638:
# ./check_ping -H 2001:6b0:e:2018::9999 -w 5000,100% -c 5000,100% -p 1 -v -v -v -6
