> Just use m_counter( b ? 1u : 0u ) or m_counter{ short(b ? 1u : 0u) }
Oops, the second one should be m_counter{ (unsigned short)(b ? 1u : 0u) }

Yes. Adding constexpr to the constructor only means that it *can* be used in
constant-expressions, n
l b = true)
: m_counter{ b ? 1u : 0u }
{}
std::atomic m_counter;
};
S x;
The compiler rejects this program too - is this correct?

--- Comment #2 from Jonathan Wakely ---
N.B. to make the code compile just don't use braces for the initialization:
: m_counter( b ? 1u : 0u )
