The following code
```
constexpr static union {
int i = 1;
} u; //ok everywhere
constexpr static union {
int k = 1;
}; //error in Clang
```
is fully accepted in GCC, and the first part `u.i` is accepted in Clang. But for the second part the error is shown:
```
union cannot be marked constexpr
```
Online demo: https://gcc.godbolt.org/z/Wd4WWq5Pn
It is either wrong compiler rejection (if GCC is right) or the error message is inexact, considering that the first `constexpr union` is accepted.
