qDebug output in QtCreator gets scrambled for long strings

#include "mainwindow.h" 

#include <QDebug>
#include <QApplication>

int main(int argc, char *argv[])
{
  QApplication a(argc, argv); 

  MainWindow w; w.show();  

  qDebug() << "------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------";   

  return a.exec();
}
