A question about "G_exception symbol"

ROOT
1

I have a question, I have a problem with a simulation, I simulated and stops and the following error “G_exception symbol” in the next part of the program:

I do not understand the error.

TGraph *p1 = new TGraph(n,T,IKI);
p1->SetMarkerStyle(1);
p1->SetLineColor(2);
p1->SetTitle(" Corriente Rapida De Sodio ");
p1->GetXaxis()->SetTitle(“t(ms)”);
p1->GetYaxis()->SetTitle(“I(uA/uF)”);
p1->Draw(“ALP”);
gPad->Update(); here

Thanks for your help, I tried several other methods, but this method is the best simulates what I want, I hope you can help me.

Could you post the shortest running script reproducing the problem and indicate your version of ROOT ?
