This is a bug report for perl from root@grommet.slackware.lan,
generated with the help of perlbug 1.33 running under perl v5.6.1.

[Please enter your report here]

Socket6 does not return ::1

Socket6 0.23

tcp connection to localhost
same result with 
server bound to in6addr_any or in6addr_loopback

vacant $PORT used for testing

client connect to in6addr_loopback

on server side
$paddr = accept($clone,$server)

returns funny netaddr

netstat -na	immediately following close

tcp        0      0 ::1:10000               ::1:60084
TIME_WAIT   
tcp        0      0 ::1:10000               ::1:60080
TIME_WAIT   

ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

unpack('C*',$paddr);
10 0 234 204 0 0 0 0 0 0 0 0 0 0 0 0 236 247 255 191 128 106 9 8 0 0 0 0

text result from unpack_sockaddr_in6_all
port, 60084, flow 0, scope 0 0:0:0:0:ecf7:ffbf:806a:908

This appears to be a flaw in "accept"
