PHP Warning: str_repeat(): Second argument has to be greater than or equal to 0 in /usr/local/share/pear/Net/IPv6.php on line 614

Here is that line in question (top being 614):

 $fill = str_repeat(':0:', 6-$c2-$c1);
                $uip  = str_replace('::', $fill, $uip);
                $uip  = str_replace('::', ':', $uip);

While IPv6 is working properly, this appears in the development snapshot builds (latest as of writing). This error repeats infinitely in my log file, it appears to be code to turn a shorter IPv6 IP into one with all 0s. But unsure why I keep getting this message other than what it says. Let me know what else I can do to assist / upload - or if there is a way to allow this file to regenerate. I seem to have it regardless of my clean installation(s). Nothing out of ordinary in network config - as this is for my home net.
