                   Vec<zz_p>& tmp2)
{
   long numDims = s.getNumDims();
   //OLD: assert(numDims > 0);
   helib::assertTrue(numDims > 0, "CubeSlice s has negative dimension number");

   if (numDims > 1) {
      long dim0 = s.getDim(0);
      for (long i = 0; i < dim0; i++)
         recursiveEval(CubeSlice<zz_p>(s, i), multiEvalPoints, d+1, tmp1, tmp2);

   long posBnd = s.getProd(1);
   for (long pos = 0; pos < posBnd; pos++) {
