Description of problem: Chronyd crashes when multiple sources are available and chronyd selects a server with a prefer suboption as the synchronisation source, I think. Version-Release number of selected component (if applicable): chrony-2.0-1.fc22.i686 How reproducible: always Steps to Reproduce: 1. Make sure there is at least one pool/server in /etc/chrony.conf. 2. Append a server entry to /etc/chrony.conf, and set prefer to it. 3. sudo systemctl (re)start chronyd 4. Wait for chronyd to select the server with prefer as the synchronisation source. Actual results: It crashes. Expected results: It doesn't crash.
