Thanks for the detailed analysis.
I've now looked further and I think this is upstream bug
http://rt.cpan.org/Public/Bug/Display.html?id=39550
which should be fixed as of 2.55 according to
http://cpansearch.perl.org/src/SHLOMIF/IO-Socket-INET6-2.56/ChangeLog
I've upgraded libio-socket-inet6-perl locally to 2.56, and it seems
to work: The output of the same test script is now:
$ perl sock.pl

Masahito, could you upgrade the package please?
If you are busy I can offer to do a one-time NMU or to maintain the
package within the Debian Perl Group.
Cheers,
gregor
