      Create QMenu with Qt::WA_DeleteOnClose attribute.
      Open it.
      Click on some action in this menu.
      Immediately click somewhere outside (in a really short time frame)
      Application crashes.

      It looks like menu is already being deleted when second mouse event is dispatched and processed.
       
      Test app and crash report are attached.
