@users is defined because it an implicit global variable. This explains why the program never exits. build_reffers keeps pushing onto the same global array and then recurses. This doesn't ever finish. This demonstrates why it is a good idea to use strict and use warnings. And why using my to delcare variables is a good idea. Not to mention the bad database design of storing join'ed values in a single field.
