While debugging I stepped about following code in
 

void CXTPReportControl::OnDraw(CDC* pDC)
 
 

CXTPReportHeader* pHeader = GetReportHeader();

CRect rcHeader = m_rcHeaderArea;
rcHeader.right = rcHeader.left + pHeader->GetWidth();
// draw header
if (pHeader)
   pHeader->Draw(pDC, rcHeader, m_nLeftOffset);
 
// draw group by box
if (pHeader)
   pHeader->DrawGroupByControl(pDC, m_rcGroupByArea);
 
Optimizing I:

if (pHeader)
{
   pHeader->Draw(pDC, rcHeader, m_nLeftOffset);
   pHeader->DrawGroupByControl(pDC, m_rcGroupByArea);
}
 
Optimizing II:

pHeader->Draw(pDC, rcHeader, m_nLeftOffset);
pHeader->DrawGroupByControl(pDC, m_rcGroupByArea);
 
Because if pHeader is really null, then it crash already in line above (pHeader->GetWidth();)
 
A a nice day
