PVS-Studio warning V501 for IT++

Gold::Gold(const ivec &mseq1_connections,
           const ivec &mseq2_connections)
{
  ...
  it_assert(mseq1.get_length() == mseq1.get_length(),
            "Gold::Gold(): dimension mismatch");
}

This assert never works.

Warning message is:
V501 There are identical sub-expressions 'mseq1.get_length ()' to the left and to the right of the '==' operator. itpp_mkl sequence.cpp 126
