PVS-Studio warning V501 for IPP Samples

void MeBase::MakeVlcTableDecision()
{
  ...
  Ipp32s BestMV =
    IPP_MIN(IPP_MIN(m_cur.MvRate[0],m_cur.MvRate[1]),
                    IPP_MIN(m_cur.MvRate[2],m_cur.MvRate[3]));
  Ipp32s BestAC =
    IPP_MIN(IPP_MIN(m_cur.AcRate[0],m_cur.AcRate[1]),
                    IPP_MIN(m_cur.AcRate[2],m_cur.AcRate[2]));
  ...
}

See the last string. The index at the end should be '3', not '2'. As a result, the error causes the minimum value to be estimated incorrectly at times.

This suspicious code was found in IPP Samples project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions to the left and to the right of the '<' operator: (m_cur.AcRate [2]) < (m_cur.AcRate [2]) me umc_me.cpp 898
