Hi Christian,

   seems to be some problem with the handling of operator<<(i+j).
The following lines work ok:

  unsigned int k = i + j;
  cout << "i = " << i << ",j = " << j << ", i+j = " << k << endl;
  printf("i = %u, j = %u, i+j = %u\n", i, j, i+j);

I think Masaharu (the author of CINT) will get back to you soon.

Cheers, Fons.
