The combination of the merged items with a grouping rows leads to a crash when displaying the tooltip.

Problem in the following source code portion:


CRect CXTPReportRow::GetItemRect(CXTPReportRecordItem* pItem, BOOL bAsMerged)
{
...
int nTopmostRow = GetIndex();
while (0 <= nTopmostRow)
{
CXTPReportRow* pTopRow = pRows->GetAt(nTopmostRow - 1);
if (NULL != pTopRow && pTopRow->IsVisible())
{
if (pTopRow->GetRecord()->GetItem(pLeftmostColumn)->GetMergeItem() == pItem
&& pTopRow->GetRecord()->GetItem(pRightmostColumn)->GetMergeItem() == pItem)
{
--nTopmostRow;
continue;
}
}

break;
}
...
}

Bad idea to perform GetRetsord () for a grouping row.
