After a simply trying, I guess, this issue is not quite difficult to be fixed.
- The current gcc 'think', our current usage is incorrect.
- But the original gcc 'think', our current usage is OK.
- The related commits is "e52beba PR debug/54694" in gcc git repo.
I shall try to consult the gcc related members for it, so we can make sure whether we need fix our code or the new gcc need be fixed.
Thanks.
