I wish I had found it earlier. One thing remains. As a result of 52023, C11 _Alignof was "fixed" to return the smallest possible alignment, but C++11 was left alone "deliberately", although "C++11 will need examining to determine what is right for alignof there". I didn't see any such discussion for C++11 or C++14 alignof(), and by my reading of the specifications, they are defined almost identically to C11 _Alignof. So I think the central issue in this bug remains open. I'll leave it to someone else whether to reopen the case.
