在以下代码中：

#include<stdlib.h>
#include<iostream>

using namespace std;

class Test {
public:
    void* operator new(size_t size);
    void operator delete(void*);
    Test() { cout<<"\n Constructor called"; }
    ~Test() { cout<<"\n Destructor called"; }
};

void* Test::operator new(size_t size)
{
    cout<<"\n new called";
    void *storage = malloc(size);
    return storage;
}

void Test::operator delete(void *p )
{
    cout<<"\n delete called";
    free(p);
}

int main()
{
    Test *m = new Test();
    delete m;
    return 0;
}

输出是：

new called
 Constructor called
 Destructor called
 delete called

但是，当我调用 new …
