It is not exactly broken. There is a still unsettled debate AFAIK about
the correct (as in RFC-compliant) behavior in respect to IPv4 mapped
address usage, which in turn reflects on the default setting of the
sysctl knob. The IETF recommendation is supposed to be changing, so
things are a bit in a flux. On the positive side, there was a suggested
fix for this on the list a while ago, see:

Perhaps this will DTRT always.
