c++ - 类构造函数中的 new 会发生什么？

Question

这是我的类定义，只是从一个更大的程序中复制构造函数。当我的析构函数执行时，它会自动释放'coeff'内存吗？我相信它确实如此，但是，我的程序在程序完成后抛出 _CrtIsValidHeapPointer(pUserData) 错误。

class Poly
{
private:
int order; //order of the polynomial
int size; //order + 1
int * coeff;//pointer to array of coeff on the heap

public:
Poly();
Poly(int Order);
Poly(int Order, int * Coeff);
~Poly(){cout << "Destructor\n";};
Poly(const Poly &rhs);

//accessors &  mutators
void set();
void set(int * Coeff, int Order);
int getorder(){return order;};
int * get()const{return coeff;};

//Overloaded Operators
Poly operator+(const Poly &rhs);
Poly operator-(const Poly &rhs);
Poly operator*(const int scale);
Poly operator=(const Poly &rhs);
Poly operator*(const Poly &rhs);
const int& operator[](int I)const;
int& operator[](int I);
bool operator==(const Poly &rhs);
int operator( )(int X);
friend ostream & operator<<(ostream & Out, const Poly &rhs);
friend istream & operator >>(istream & In, Poly &rhs);
};

Poly::Poly(const Poly &rhs)
{
order = rhs.order;
size = rhs.size;
int *coeff = new int[size];
for(int i(0); i <= order; i++)
    coeff[i] = rhs.coeff[i];
}

谢谢

析构函数只会cout << "Destructor\n" .它不会释放任何内存。
