XTP 12.0.1, but I think this is present in all versions.
 
class CMyPane : public CXTPFrameWndBase<CWnd>
...
int CMyPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CXTPFrameWndBase<CWnd>::OnCreate(lpCreateStruct) == -1)
         return -1;

    InitCommandBars();
    ...
}
 
In my application this window is created, destroyed and then created again - without destroying the CMyPane-object:
 
m_myPane.Destroy();
...
m_myPane.Create(...); // MEMORY LEAK!
 
 
The error lies in XTPFrameWnd.h. Obviously, you don't think about the above scenario!
virtual BOOL InitCommandBars(CRuntimeClass* pCommandBarsClass = RUNTIME_CLASS(CXTPCommandBars))
 {
    // Begin FIX
    if (m_pCommandBars)
    {
        m_pCommandBars->InternalRelease();
    }
    // End FIX
    ASSERT(pCommandBarsClass->IsDerivedFrom(RUNTIME_CLASS(CXTPCommandBars)));
    m_pCommandBars =  (CXTPCommandBars*) pCommandBarsClass->CreateObject();
    ASSERT(m_pCommandBars);
    if (!m_pCommandBars)
        return FALSE;
    m_pCommandBars->SetSite(this);
    m_pCommandBars->EnableDocking();
    return TRUE;
}

Hmmm, why not destroy the command-bar in OnDestroy()?
