Jiang An <de34 at live dot cn> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |de34 at live dot cn --- 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).
