I am not really sure about the underlying reason for this issues, but I can contribute another workaround.

    {

         TFile f("oo.root");
         TH1& rh = *h;
         rh.Divide(h0);
         rh.Divide(h1);

The reference `rh` can of course be reseated.

This issue seems to be a limitation in either CINT or the ROOT API (not sure where), but it always good for a confusing moment. I think it would be great if this could be fixed.
