Hi Rooters, The following simple macro causes a segmentation violation if I uncomment the mfile->Update line. This is ROOT 2.22/09, CINT 5.14.8. -B -- { TH1S *monhisto = new TH1S("eventnr","event_nr",101,-0.5,100.5); TH1S *monhisto2 = new TH1S("eventnr2","event_nr2",101,-0.5,100.5); mfile = TMapFile::Create("onhistos.map","RECREATE", 10000000,"blabla"); mfile->Add(monhisto,"eventnr"); for (Int_t i = 0; i < 52; i++) { monhisto->Fill(i); } monhisto2->Add(monhisto,monhisto2); //mfile->Update(monhisto); mfile->Close(); monhisto2->Draw(); }
