Hello ROOT team

I don't understand why the following few lines result into ROOT crush

root [0] TGraph2DErrors * g = new TGraph2DErrors()
root [1] g->SetNameTitle("a", "b")
root [2] g->SetPoint(0, 1.0, 1.0, 1.0)
root [3] g->SetPointError(0, 1.0, 1.0, 1.0)

I have tested on ROOT version 5.16/00 (lxplus) and 5.20/00 (my laptop). Any explanation ?

Thanks,

            Margar
