what version of ping are you using? I was unable to replicate this with
either the debian iputils-ping package version 3:20161105-1, or with
debian inetutils-ping package version 2:1.9.4-2+b1. neither of them seem to
do a getnameinfo() at all if it is initially supplied with an IP
address.
That said, with the same last line of /etc/hosts, getent is willing
to pass along the garbage chars:
0 test@host:~$ getent hosts 127.0.0.3
127.0.0.3 ; ZZZ
^[G0
0 test@host:~$ 0
bash: 0: command not found
127 test@host:~$
