They are "errors reported by Control Flow Integrity" - that part is true. This is valid C++, but it triggers false positive errors in CFI.
This is not without precedent - see https://github.com/llvm/llvm-project/commit/3e58a6a7, https://github.com/llvm/llvm-project/commit/f11c00d7 and more.
The fact that CFI is stricter that the wording of the standard has been discussed many times before, but the conclusion is always that these reports are useful.
This type of false positive is not common at all outside of libc++.
