Customer description:

We are see a regression bug between sip6-6.5.1 and sip6-6.6.2. Basically code like this no longer works and results in a compilation error while doing the sip-build.

Define the value or impact to you or the business
This bug was impeding our progress towards moving to el9 since it was breaking builds of internal software. As a short term stop gap we can downgrade to sip6-6.5.1 on our build machine. But that is not a tenable long term solution.
