Hi,

To simulate a crash recently found in my code, I wrote a simple code
treetest.C.

The following code runs ok in root 2.23.12 but crashes in root 2.24.05,
could anybody tell me the reason and how to fix it ? 

I saw it on linux machine.

Thanks!

void treetest(){
    Int_t              bufSize=32000;
    Int_t              splitLevel=0;   

    TFile* file      = new TFile("File.root", "RECREATE");
    TTree* tree      = new TTree("Tree", "A Foo Tree");
    TObjArray* theArray= 0;

  TBranch* br=tree->Branch("tree","TObjArray", &theArray,
bufSize,splitLevel);

   for (Int_t j=0; j < 10; j++){

    theArray=new TObjArray();

    TGraph* graph1 = new TGraph();
    TH1F* graph2 = new TH1F("foo","foo",0,10,10);

      for (Int_t i = 0; i < 10; i++) {
      graph1->SetPoint(i, i, i+1); 
      graph2->Fill(i);
    }

     theArray->AddLast(graph1);
     theArray->AddLast(graph2);
  
       tree->Fill(); // <========crash here
   }


    //  tree->Print(); 
    tree->Write();
    file->Close();
   


  }
