编译bug？？

[pcvvv]

class A
{
public:
    A()
	{
		cout << "Constructors default A" << endl;
	}
	virtual ~A()
	{
		cout << "Destructors A" << endl;
	}
    int x;
};
class AA :public A
{
public:
    AA()
	{
		cout << "Constructors default AA" << endl;
	}
	virtual ~AA()
	{
		cout << "Destructors AA" << endl;
	}
    int x;
};
int main()
{
	A *p=new AA[2];
	p->x=10;
	cout<<"x="<<p->x<<endl;
	delete []p;
}

clang version 3.4.2 输出为

Constructors default A
Constructors default AA
Constructors default A
Constructors default AA
x=10
Destructors A
Destructors A

没调用AA析构
而g++ 4.8.3 输出为正常的

Constructors default A
Constructors default AA
Constructors default A
Constructors default AA
x=10
Destructors AA
Destructors A
Destructors AA
Destructors A

这是clang++的bug？

你代码是错误的

A *p=new AA[2];

不能这么干. 只能

AA *p=new AA[2];

未定义行为，微软“完美”解决了这个问题, 导致认为其他编译器有bug。不要尝试这个。
