It's a bug (and obviously applies to any scoped enumeration, not just
std::byte).
enum class byte : unsigned char { };
using uint8_t = unsigned char;
struct Test
{
byte a : 2 = byte{0}; // NOK
uint8_t b : 2 = 0; // OK
};
I assume it simply hasn't been implemented yet. Could you please
report it to bugzilla?
