Enhancement request in yacc compiler for ipfilter to support more than 68 ippools

Using IP Filter: v4.1.13 (480) on AIX 6.1, 7.1 and 7.2, I observed
that creating an ippool with more than 68 ip addresses in it doesn't
work as expected.
It doesn't give any error while creating an ippool, but when we try to
list the pools using ippool -l, it doesn't list that particular pool
with more than 68 ip's.
Moreover, we can create a ipfilter rule with that ippool - id, but it
doesn't filter the traffic as expected.

    IBM has no plans to invest in updates to IPFilter in the future, as AIX has other firewall capabilities that are supported. IBM has added the ported IPFilter source code to the AIXOSS Github area at https://github.com/aixoss/ipfilter. You may open an issue there to discuss this problem.

    We have many customers waiting for this issue to get resolved and hence need it (atleast the ETA) as early as possible.

    The YACC compiler issue was concluded by IBM support team in PMR:41779082000
    On running ippool -f /tmp/ippool.conf -dnv, the stack overflow message is thrown for YACC compiler

    Hi. I don't understand how you've decided this relates to YACC. Do you believe this is a bug in the YACC parsing, or YACC using a buffer that's too small?
