@LunNova I cannot update your PR here:

Can you see whether this patch would work for you?

@tcgu-amd mentioned this approach will still cause a problem for roctracer because it's on too old a C++ version to support this syntax and depends on this API.

Locally I am able to build with this PR and it looks good.

So I think David's PR should be able to fix the issue.
