<pre>Consider the example:
struct A {
A();
A& foo();
A* operator->();
};
struct B {
B(A&);
};
struct composed2 {
B b_;
A a_;
composed2() : b_(a_->foo()), a_() {} // does not warn!
//composed2(int) : b_(a_.foo()), a_() {} // warns
};
We are calling an operator-> on a uninitialized variable `a_`, but the
diagnostic is missing.
