Guys,
Could someone tell me why the Progam Crashes. Here is the Code ...

Qt Code:

Switch view

#include <qapplication.h>
#include <qguardedptr.h>
class Employee{
public:
    Employee( const QString& strName, int iSal ){
        m_strName = strName;
        m_iSalary = iSal;
    }
 
    QString name() const {
        return m_strName;
    }
    void setName( const QString& strName ){
        m_strName = strName;
    }
 
    int salary() const {
        return m_iSalary;
    }
 
    void setSalary( int iSal ) {
        m_iSalary = iSal;
    }
 
    operator QString() const {
        return m_strName + ", " + QString::number( m_iSalary );
    }
 
private:
    QString m_strName;
    int     m_iSalary;
};
 
 
int main(int iArgs, char* aszArgs[] ) {
    QApplication app( iArgs, aszArgs );
 
    QMap< int, QGuardedPtr<Employee> > mapIdToEmployee;
    mapIdToEmployee[ 0 ] =  new Employee( "Sunil", 6000 );  //Crashes ??
 
    if( ! mapIdToEmployee[0] ){
        qWarning( "Employee Destroyed !!! " );
    }
    else{
        qWarning(  ( static_cast<QString>(*mapIdToEmployee[0]) ).ascii() );
    }
    return  0;
}
