Hi Naresh, Can you tell me more about your specific version of clang-17?
I believe a fix of mine to clang should address this. It landed in clang-18, and was backported to clang-17 recently. https://github.com/llvm/llvm-project-release-prs/commit/0b2d5b967d9837579389...
I suspect your clang-17 might need a rebuild. Thanks for the report.

I will rebuild / re-test and confirm soon.

Thank you !

Ok, decoding that we have 2023-07-25...

And the backport (that sha above) landed 2023-08-03 so that checks out. So yes, the initial report was missing the fix that landed more recently.
