    i am trying to create two qtimers and each one should fire at different time
    in a console application```

       QApplication a(argc, argv);
      int counter=0; 
      QTimer timers[1] ;
        for (int k=0; k<2; k++)
        {
            timers[counter].singleShot(5000+counter*1000, [&](){
                TimerUpdate("");
            });
            counter=counter+1;
        }
    

    void TimerUpdate(Qstring job)
    {
    //do thing
    }

    
    this code has an error in the QTimer initialization when it is more than 1. As long as k<1 in the loop it works fine.
    The error is assert fail, index out of range !

      QTimer timers[1] ;

      that is an array with ONE element, not TWO.

      Regards

      Qt has to stay free or it will die.

        Thank you for the check. When i inspected my code again, i found that it was made 2, but the mistake was somewhere else in an internal loop trying to call an item in a qlist that is not found.
