TCanvas with same name

Hi Roottalk,

I've noticed a number of problems that occur when creating two TCanvases with the same name, ranging from crashing up to hard-to-track-down memory corruption. As an example, consider:

  TCanvas* c = new TCanvas("foo");
  TCanvas* c2 = new TCanvas("foo");
  delete c;
  c2->Draw();

which crashes with development ROOT.

So, could we have a warning printed when creating a canvas with the same name as an existing one (like the one printed for same-named histograms)?

Thanks,
