Another test:

struct T 
{ 
    int x = 0; 
    bool y = 0; 
    constexpr T() {}
};

int main()
{
    constexpr T t = (T{} = T{});
}

prog.cc: In function 'int main()':
prog.cc:10:31: error: accessing value of '<anonymous>' through a 'char [5]'
glvalue in a constant expression
     constexpr T t = (T{} = T{});
                               ^

That looks rather bad.
