Summary0002698: memory leak in vtkMath::SolveLeastSquares
DescriptionA memory leak was found in the method
int vtkMath::SolveLeastSquares(int numberOfSamples, double **xt, int xOrder,
                               double **yt, int yOrder, double **mt, int checkHomogeneous);

the intermediate variables are not released when this function returns 0;
Thus, the code:
*****************begin code**************
 // clean up:
  // set up intermediate variables
  for (i = 0; i < xOrder; i++)
    {
    delete [] XXt[i];
    delete [] XXtI[i];

    delete [] XYt[i];
    }
  delete [] XXt;
  delete [] XXtI;
  delete [] XYt;
  delete [] homogenFlags;
****************************************
should be inserted just before the return(0);
this bug seems to be present in all the versions
