Re: Bug in TGraph2D 5.28

Noel,

there's an issue with construction/destruction ordering given that neither TGraph(2D) has a name, so after the construction the same object will be deleted due to it's reference going away.

That said, I see the same in CINT:

root [0] g = new TGraph(3);
root [1] g->GetN()
(const Int_t)3
root [2] g2 = new TGraph2D(3);
root [3] g2->GetN()
(const Int_t)0
root [4]

so there must be something more to it ...
