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/0b2d5b967d98375793897295d651f58f6fbd3034

I suspect your clang-17 might need a rebuild.  Thanks for the report.
