SYMPTOMS
When you try to close a Microsoft Foundation Class (MFC) program that was created in Microsoft Visual Studio .NET 2003, the program may unexpectedly quit (crash). This behavior may occur when the following conditions are true:
 * The program is written in Microsoft Visual C++ .NET 2003.
 * The program uses the CToolBar class.

When you examine the call stack information, you notice that the program unexpectedly quits when the CFrameWnd::DestroyDockBars method is executed.



CAUSE
This problem occurs because the MFC program tries to delete child controlbar objects two times. The MFC program maintains an internal list of all dockbar objects in the program. When the DestroyDockBars method is called, the method deletes all the dockbar objects in the program and also deletes the child controlbar objects. Then, the program tries to explicitly delete the child controlbar objects again.
