Here is the program...

class CopyCon
{
public:
char *name;

CopyCon()
{ 
    name = new char; 
}

CopyCon(const CopyCon &objCopyCon)
{
    name = new char;
    _tcscpy(name,objCopyCon.name);
}

~CopyCon()
{
    if( name != NULL )
    {
        delete name;
        name = NULL;
    }
}
};

int main()
{
    CopyCon objCopyCon1;
    objCopyCon1.name = "Hai";
    CopyCon objCopyCon2(objCopyCon1);
    objCopyCon1.name = "Hello";
    cout<<objCopyCon2.name<<endl;
    return 0;
}

Once the code execution completes, when the destructor called, it crashes on 'delete' saying...

Debug Error!

Program: ...

HEAP CORRUPTION DETECTED: after Normal block (#124) at 0x00366990. CRT detected that the application wrote to memory after end of heap buffer.

Don't we have to clear the heap memory in destructor. What's wrong with this program? Pls someone help! Copy constructor works perfectly as intended. But still... !?
