Hi,

we see the false-positive behavior of -Wno-self-assign-overloaded flag in case of subtraction assignment operator. 
The minimal reproducer that we got: https://godbolt.org/g/8PQMpR

  typedef int Int_t;
  typedef double Double_t;
  class TObject {};
  template <class Element> class TMatrixTBase : public TObject {};
  template <class Element> class TMatrixT : public TMatrixTBase<Element> {
  public:
    enum EMatrixCreatorsOp1 {
      kZero,
      kUnit,
      kTransposed,
    };
    TMatrixT(){};
    TMatrixT(Int_t row_lwb, Int_t row_upb, Int_t col_lwb, Int_t col_upb){};
    TMatrixT(EMatrixCreatorsOp1 op, const TMatrixT &prototype){};
    TMatrixT<Element> &operator-=(const TMatrixT<Element> &source){return *this;};
  };
  
  typedef TMatrixT<Double_t> TMatrixD;
  void stress_binary_ebe_op(Int_t rsize, Int_t csize) {
    TMatrixD m(2, rsize + 1, 0, csize - 1);
    TMatrixD m1(TMatrixD::kZero, m);
    m1 -= m1;
  }

Thanks in advance!
