Application is getting crashed ..while adding elements to QTableView

[M_31]

I have used QTableView to display my result value and i have QlistWidget to select which result should be displayed in my QTableView.

here is the code ..
@

void CResultModel::listSelected(QModelIndex& index)
{
int nRow = index.row();
if( m_listResults.size() > nRow )
{
CResult *result = m_listResults.at( nRow );
if( result )
{

             QList<CMyResult* > item = result->m_listMyResult ;
             addItems( items );
      }
 }

}

void CResultModel::addItems( QList<CMyResult*> items )
{
clearAll();

beginInsertRows(QModelIndex(), 0, items.size() -1 );
m_listMyResult = items;
endInsertRows();
}

void CResultModel::clearAll()
{
if ( m_listMyResult.size() > 0 )
{
beginRemoveRows(QModelIndex(), 0, m_listMyResult.size() -1 );
m_listMyResult.clear()
endRemoveRows();
}
}

@

From this code i am able to see my different result in my QtableView...but after certain time...my Application is getting crashed... even if i didnt do any operation in my application...

finally its showing the error on
@
inline bool QBasicAtomicInt::ref()
{
unsigned char ret;
asm volatile("lock\n"
"incl %0\n"
"setne %1"
: "=m" (_q_value), "=qm" (ret)
: "m" (_q_value)
: "memory");
return ret != 0;
} @

Please let me know..whether i am doing anything wrong on this...

Silly question: are you sure there is not a delete somewhere that is causing the crash? Usually this happens if you reference a memory location that no longer exists (or never existed).
