C++ program crashes

Hi,

Can anyone tell me why the below program is crashing? and where exactly it is crashing. What is the corrective measure to be taken to make it work fine?

Code:
#include <iostream>
#include <cstring>
using namespace std;

class CString {
    char* m_data;

public:
    CString() : m_data(NULL) { }

    CString(char* t) {
        m_data = new char[strlen(t) + 1];
        strcpy(m_data,t);
    }

    operator char*() {
        cout << "function called " << endl;
        return m_data;
    }

    ~CString() {
        delete m_data;
    }
};

int main() {
    CString str1 = "Hello";
    CString str2 = str1;
    cout << str1 << endl;
}

request_scroll(3alleg4) 					  Allegro manual					   request_scroll(3alleg4)

NAME
request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library. SYNOPSIS
#include <allegro.h> int request_scroll(int x, int y); DESCRIPTION
This function is used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running other code in the meantime and use the poll_scroll() routine to detect when the flip has actually taken place. Triple buffering is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see if it will work with the current driver. RETURN VALUE
This function returns zero on success, non-zero otherwise. SEE ALSO
poll_scroll(3alleg4), request_video_bitmap(3alleg4), gfx_capabilities(3alleg4), scroll_screen(3alleg4) Allegro version 4.4.2 request_scroll(3alleg4)
