You might have better luck sharing this on StackOverflow. This is not a support forum, it is one for reporting compiler/language bugs and suggestions.
If you believe you are running into a compiler bug, please share a minimal repro project that demonstrates the issue you are running into and why you believe this is a compiler bug and not a declaration file issue or library usage problem.
