Can you run the helper standalone with valgrind ?
e.g.
./negotiate_kerberos_auth_test squid.example.com 3 | awk
'{sub(/Token:/,"YR"); print $0}END{print "QQ"}' |
valgrind --log-file=./negotiate_kerberos_auth.val --leak-check=full --show-reachable=yes
-v ./negotiate_kerberos_auth -d -t none -k $dir/squid.keytab -s

At moment a helper will call exit(0) after 10000 requests.
good to know that there aren't any general objections.
Here is one: Squid is currently not designed to gracefully handle a
helper-initiated exit/death. Helpers that decide to exit may kill
in-progress transactions, and/or may slow down or even kill Squid,
depending, in part, on your Squid version and/or configuration.
AFAICT, there are a few better options for going forward, including:
1. Fixing helper memory leak (just stating the obvious for completeness
sake).
2. Wrapping leaking/exiting helper process into a
non-leaking/non-exiting helper that is going to kill/restart the wrapped
helper after N requests (transparently to Squid).
3. Hacking Squid to kill/restart a helper process after N requests.
4. Enhancing Squid and helper protocol to handle helper-initiated exits.
HTH,
Alex.
