Dear Maintainer,
* What led up to the situation?
configuring ipv6 address for a hostname in /etc/hosts and ipv4 target
address in rsyslog.conf action.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Steps to recreate
1. Edit /etc/hosts file and add the following line
fe80::2204:fff:fef7:3dbe dns6
2. Edit /etc/rsyslog.conf and add the following two lines.
$template MyFormat,"<%pri%>1 %timegenerated:::date-rfc3339%
%hostname% %app-name% %procid% %msgid% %structured-data%
%%!msg1%"
*.info action(type="omfwd" Target="dns6" Address="100.1.2.61"
Device="mgmt" Port="514" Protocol="udp" Template="MyFormat")
3. run rsyslogd daemon and observe crash.
root@docker-core:/# /usr/sbin/rsyslogd -n
Segmentation fault
* What was the outcome of this action?
rsyslogd crashes with the following trace

* What outcome did you expect instead?
rsyslogd can print a error log but shouldn't crash.
