App crashes if you press the ESC key

[mself]

On Mac, the app crashes if you press the ESC key.

I see this code in MainWindow::keyPressEvent():

#ifdef MYDEBUG
        case Qt::Key_Escape:
            g_data->stopAndWaitAudioThread();
            qApp->closeAllWindows();
        break;
#endif // MYDEBUG

But the app crashes with EXC_BAD_ACCESS in the call to makeCurrent() in VibratoTunerWidget::~VibratoTunerWidget():

VibratoTunerWidget::~VibratoTunerWidget()
{
  // Remove display lists
  makeCurrent();

  glDeleteLists(m_dial, 1);
  glDeleteLists(m_needle, 1);
}

I don't understand what the value is of this "debug" feature?

I wonder it could be to have way to quit when GUI is frozen (like for me in play and record due to RtAudio callback looping)

App return properly on my side
