Built using gcc 5.3.0.

--
When udev debug output is enabled, either via kernel parameter or in
`/etc/udev/udev.conf`, the stderr of `dumpcap -D` contains a few lines, which
none of the frontents is unable to parse properly. As a result, tshark,
wireshark-qt and wireshark-gtk are unable to enumerate interfaces and don't
work.

To reproduce:

* edit `/etc/udev/udev.conf` on your system, add:

   udev_log="debug"

* restart wireshark
