  Nterm *result = GETMEM(Nterm *, poly_size_);

  result->coeff = 0;  // This value is never used, one hopes...
  // In fact, it gets used in the line below:       K->remove(tmp->coeff);
  // which is called from the line below:           remove(idiotic);
  // and it crashes there, because this assignment only sets the integer
  // part of the union, so on a machine with 4 byte ints and 8 byte pointers,
  // the
  // pointer part is not NULL!
  result->coeff.poly_val = nullptr;  // so I added this line
