Hi, Rooters.
We are trying to work with TMapFiles here, and I found the following
simple macro causes seg faults if I do not comment out the mfile->Close()
line at the end of the file. Other perturbations such as
monhisto->DrawCopy() have the same behavior. Operations on the copy
after mfile->Close() such as GetBinContent also cause segfaults.
I doing something wrong, or is there a bug somewhere?

{
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);
mfile->Update();
}
monhisto2->Add(monhisto,monhisto2);
monhisto2->Draw();
mfile->Close();
}
