I couldn't reproduce the problem simply by configuring a secondary
server that has more than two masters like this:

zone "" {
     type slave;
     file "";
     masters {;; };

and then reloading the server.  There should be some other reason that
triggered the assertion failure in your case.  Can you provide more
details, including a complete copy of your named.conf and detailed
steps to cause the failure?
