Hi Jonathan,

of course you are true. (I was overhasty with my bug report.)

Now I changed my program to using a constexpr-ctor:

#include "atomic"

struct S
{
    explicit constexpr S (bool b = true)
    : m_counter{ b ? 1u : 0u }
    {}

    std::atomic<unsigned short> m_counter;
};

S x;

The compiler rejects this program too - is this correct?

Wolfgang

N.B. to make the code compile just don't use braces for the 
initialization:

    : m_counter( b ? 1u : 0u )
