Um, "localhost" is not a good name for this ACL.

That name has a special meaning in networking as the 127.0.0.0/8 range,
which is handled specially on NIC.

I like to recommend localnet for this, others prefer our_networks.
Something to refer to the internal LAN range.

Squid consumes memory for all sorts of things. Cache indexes are only
one (admittedly large) amongst many.

That config shows nothing relating to memory. Though if it is a leak, it
likely won't show there anyway.

Is there any other trace you know how to do that would show memory usage
within an app?

Squid when built with it has valgrind (alleyoop) support, for real-time
leak checks through the cachemgr interface.
