Does truly look like a bug.
Can you register this as a bug with as much info as you can get on it in
STABLE8. This gets a little technical for squid-users now. I'll follow up
further in bugzilla so we can track the issue properly.

For bugzilla this extra info will be helpful:
You earlier located the debug message indicating AuthUser. Is that still
present exactly the same? or has it changed?
We are going to have to track down; firstly what object is not being
released, and then why thats happening.

Thank you.
