[David Kastrup <dak@xxxxxxx>]

This is an upstream bug.  I read in a source repository (mirror?)
https://github.com/jackaudio/example-clients/blob/master/server_control.c#L151-L154

	struct option long_options[] = {
		{"driver", 1, 0, 'd'},
		{"client", 1, 0, 'c'},
	};

This is missing a final entry {0, 0, 0, 0} to end the array.  Does
anybody have an idea who to contact?
