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;
}

XmScrollVisible(3X)													       XmScrollVisible(3X)

NAME
XmScrollVisible - A ScrolledWindow function that makes an invisible descendant of a ScrolledWindow work area visible SYNOPSIS
#include <Xm/ScrolledW.h> void XmScrollVisible (scrollw_widget, widget, left_right_margin, top_bottom_margin) Widget scrollw_widget; Widget widget; Dimension left_right_margin; Dimension top_bottom_margin; DESCRIPTION
XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function repositions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location rela- tive to the viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the ScrolledWindow widget be set to XmAUTOMATIC. Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant. Specifies the ID of the widget to be made visible. Specifies the margin to establish between the left or right edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved horizontally to make it visi- ble. Specifies the margin to establish between the top or bottom edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved vertically to make it visible. For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3X). SEE ALSO
