136	Sparse images may cause the encoder to hang when ALF is on (observed only in release build)	minoo		"The calculation of ALF coefficients is not robust for very sparse images. 
Simplest solution: 
Check the returned value by gnsSolveByChol(). 
If the return value indicates a singular case then assign filter 
coefficients arbitrarily

#ifndef MOT_SPARSE_FIX
  gnsSolveByChol(E, y, filterCoeff, sqrFiltLength);
#else 
  int singular = gnsSolveByChol(E, y, filterCoeff, sqrFiltLength); 
  if(singular == 0)
  {
          filterCoeff[0] = 1;
	  for (i=1; i<sqrFiltLength; i++)
		  filterCoeff[i] = 0; 
  }
