Experiencing the same problem (hosts with more than one AAAA record do not work) with stock install of squid3 3.1.6-1.1 on multiple computers.
NB. bugs.debian.org today has just one AAAA address (and works) but packages.debian.org still has two and security.debian.org also fails with three. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
