Hi rooters,

I have the following problem, which to my mind comes from my bad knowledge of C++. If I run twice the small script below,

void test()
{
   TString path = "/user/deserevi/PH176/Analyse/";
   TString name = "fl18_cib*_new.root";
   path += name;
   TChain *ch = new TChain("coinc");
   ch->Add( path );
   cout << "OK 1" << endl;

   ch->Draw("energie_exc>>h(3000, 5000, 8000)");
   cout << "OK 2" << endl;
   TH1F *h5 = (TH1F*) h->Rebin(5,"h5");
   cout << "OK 3" << endl;
   h5->Draw();
   cout << "OK 4" << endl;
}
 

I obtain the following error just before executing the  TH1F *h5 = (TH1F*) h->Rebin(5, "h5") ' line.

 *** Break *** segmentation violation
