Actually, it doesn't need a constructor. The presence of _any_ member function
triggers the bug:

static assert({
    struct Result {
        void foo(){}
    }
    Result x;
    return true;
}());

If it doesn't have any member functions, then it is actually a static nested
struct. So true nested structs are never supported in CTFE.

It's because the hidden member of the struct needs a pointer to the enclosing
function, and this is not implemented.
