bugprone-parent-virtual-call

检测并修复对祖父母虚拟方法的调用，而不是对重写父类虚拟方法的调用。

struct A {
  int virtual foo() {...}
};

struct B: public A {
  int foo() override {...}
};

struct C: public B {
  int foo() override { A::foo(); }
//                     ^^^^^^^^
// warning: qualified name A::foo refers to a member overridden in subclass; did you mean 'B'?  [bugprone-parent-virtual-call]
