@steakhal, thank you for the quick turnaround with the fix!

A backport for the next point release of 18 would be very much appreciated.

We are using the scarthgap branch of openembedded meta-clang layer, which has clang-18.  Since that is an LTS branch, I expect that we will be using clang-18 for a while.

Thanks again!
