Hi,

it appears that I have stumbled across a bug, or so I believe. I've noticed that If you have a THStack and you save the TCanvas as ".C" upon executing this macro I get a crash: error: Symbol THSTack1 is not defined in current scope

However, it turn out that this can be avoided be setting: myTHStack->SetHistogram( (TH1D*) myTHStack->GetHists()->At(0));

Is there a way to avoid this because it gives rise to other problems - like replacing the histogram (TH1D*) myTHStack->GetHists()->At(0) in memory.

I have attached the macro reproducing the problem. I am running ROOT 5.28.
