在构造函数初始化程序中为成员指针指定另一个成员的地址是标准C ++吗？

Question

Does this conform to the standard?

class Foo {
    Bar m_bar;
    Bar * m_woo;
public:
    Foo() : m_bar(42, 123), m_woo(&m_bar) { }
};

Answer 1

It is correct. What is not correct is dereferencing that pointer before that particular subobject has been fully initialized.
