Hi,
I'm running Root v4.04/02 on Windows XP under cygwin. I chain up several files using TChain and run on a tree. After the code has run over all events, I get segmentation fault (code and backtrace below). Changing the last file on the chain doesn't make a difference. My guess is there should be some sort of a closing statement at the end which is missing?
Thanks in advance for any help- Lashkar
Code:
void main()
{
TChain chain("CBNT/t3333");
chain.Add("~/R-hadron_sim_files/py_mass500.1_154betarec1/filled.beta.51.root");
chain.Add("~/R-hadron_sim_files/py_mass500.1_154betarec1/filled.beta.52.root");
Double_t beta;
Int_t fCurrent=-1;
Long64_t nevents = chain.GetEntries();
chain.LoadTree(0);
chain.GetEntry(0);
TLeaf *lbeta = new TLeaf();
lbeta = chain.GetLeaf("beta");
for (Int_t nev=0;nev<nevents;nev++)
{
chain.LoadTree(nev);
if (chain.GetTreeNumber() != fCurrent)
{ chain.GetTree(); chain.SetBranchAddress("beta", &beta); lbeta = chain.GetLeaf("beta"); fCurrent = chain.GetTreeNumber(); cout<<"fCurrent = "<<fCurrent<<endl; }
