app crash on close, view is destroyed twice

My app crash on close because of a memory heap corruption due to view double destruction.

My app use a splitter with some views loaded at oncreateclient method on frame and I think it interfere with normal mfc document view architecture workflow.

I tryed to debug inside my app and inside mfc in order to understand why my views are destroyed twice but I didn't understand. One thing I'm sure, I'm not destroying them from my app, this double destroying is done from mfc.

Can anyone give me a suggestion?

Thank you.

How did you create the views? By default the view windows are created when their parent frame window is created by the document template. I did not have used splitter frames so far, but it should be handled in a similar way. So your view creation may interfere with the MFC handling of views.

I would suggest to put a breakpoint in the MFC CView::~CView function and see, where the double destroy comes from.

Note that views are normally destroyed in the OnDestroy member function with
