dig/host do not fail over to other name servers in /etc/resolv.conf upon UDP timeout
When a query to the first nameserver in /etc/resolv.conf fails, /usr/local/bin/host terminates silently.
BIND version used
Only bind-tools of this version: package version is 9.18.3
Steps to reproduce
Connecting the first NS in resolv.conf returns EHOSTUNREACH or EPERM (ECONNREFUSED does not create the problem).
What is the current bug behavior?
no output from "host whatever"
What is the expected correct behavior?
The second nameserver from resolv.conf should be asked
Correct behaviour is present in 9.16.29, and also when invoking "host -T"
