This code from PR 103295 is kinda related, which GCC, EDG and MSVC all accept,
but Clang doesn't:
struct S
{
union {
char buf[8];
char* ptr;
};
unsigned len;
constexpr S(const char* s,

Okay, one last simplification for posterity.
constexpr void bar() {
union {

constexpr U() {} // no active member
};
constexpr bool
