***检测到glibc***/parent_child_conscall:双重空闲或损坏(fasttop）:0x09d9

我的代码包含两个类。

  class points{
            char *p;
    public: points(){cout<<"constructor points called"<<endl;p=new char();}
            virtual ~points(){cout<<"destructor points called"<<endl;delete(p);}
  };
  class otherpoints: public points{
                    points x1;
    public: otherpoints(){cout<<"constructor otherpoints called"<<endl;x1=points();}
            ~otherpoints(){cout<<"destructor otherpoints called"<<endl;}
  };
  int main(int argc, char *argv[])
  {
    otherpoints y1;
    return 0;
  }

在这里，我在基类构造函数中分配一个指针，并在相应的基类析构函数中销毁指针的内存。

当我使用valgrind运行二进制文件时，它会给出错误：-

无法知道我无法释放哪一个1字节内存

我必须发布回溯报告吗？

任何帮助都是感谢。
