Unexpected behaviour you saw

systemd-resolved occasionally runs into a segfault when trying to resolve an mDNS service via resolvectl.

resolvectl output:

Resolve call failed: Remote peer disconnected

systemd-resolved logs:

Jun 03 11:53:37 image systemd[1]: systemd-resolved.service: Main process exited, code=dumped, status=11/SEGV
Jun 03 11:53:37 image systemd[1]: systemd-resolved.service: Failed with result 'core-dump'.

Steps to reproduce the problem

1. Run systemd-resolve --set-mdns=yes --interface=enp0s3
2. Run resolvectl --type=SRV service XStream_Smart_Box_00-xxxxx._googlecast._tcp.local
