Assume I get one parent squid A, and one child squid, B.
B's IP (v6) is in the parent's config file, like

acl children src fd00::d02/128

B's config has the line like

cache_peer fd00::316 3128 3130 default

or

cache_peer [fd00:316] 3128 3130 default

and some lines like

always_direct deny some-domain-based-acl
always_direct allow all
never_direct allow some-domain-based-acl
never_direct deny all

In this situation I'm starting to get these lines on B:

TCP connection to fd00::316/3128 failed

In the same time I can connect from B's console (telnet fd00::316 3128).

That's too easy to explain. I think the situation when I discover and
report this bug first time for like 10 years is quite impossible.
