dnsmasq 2.90 hangs at 100% cpu, dns lookup fail

This issue was reported in Alpine, and on the upstream dnsmasq mailing list

Describe your issue

What's the expected behaviour?

Activating wifi or 4G should update DNS resolution and can access internet.

What's the current behaviour?

Since last edge update, even after reboot, wifi or 4G, no internet access.

ping google.com => bad address 'google.com'

If I put nameserver 8.8.8.8 in /etc/resolv.conf, works as expected.

Process dnsmasq eats 100% CPU.

Packages installed:

• dnsmasq-common-2.90-r0
