--- Comment #3 from Jiang An <de34 at live dot cn> ---
CWG2823 has been voted into the standard (see https://wg21.link/p3046r0,
https://wg21.link/n4972).

> Should it be possible to dereference a null pointer in a C++20 constant expression?

Now such derefencing is clearly UB and needs to cause constant evaluation
failure (not only in C++20, IMO).
