Dear ROOT experts,
I have the following problem: I try to execute a modified version of the TMVA tutorial file TMVAClassificationApplication.C after training and testing of a BDT and some neural nets (DNN and MLP). When I want to input the signal file and essentially trying to do this:
TMVA::Reader *reader = new TMVA::Reader( "!Color:!Silent" );
...
float zzed_hadronic_jetNo = 0.;
float zzed_hadronic_subjets_E1 = 0.;
reader->AddVariable( "zed_hadronic_jetNo[0]", &zzed_hadronic_jetNo );
reader->AddVariable( "zed_hadronic_subjets_E1[0]", &zzed_hadronic_subjets_E1 );
...
TFile *inputS_qqH(0);
inputS_qqH = TFile::Open("/inputdirectory/wzp6_ee_qqH_ecm240.root", "UPDATE");
TTree* theTree = (TTree*)inputS_qqH->Get("events;1");
theTree->SetBranchStatus("zed_hadronic_jetNo", 1);
theTree->SetBranchStatus("zed_hadronic_subjets_E1", 1);
std::vector<float> *zed_hadronic_jetNo = 0;
std::vector<float> *zed_hadronic_subjets_E1 = 0;
theTree->SetBranchAddress( "zed_hadronic_jetNo", &zed_hadronic_jetNo );
theTree->SetBranchAddress( "zed_hadronic_subjets_E1", &zed_hadronic_subjets_E1 );
Long64_t nentries = theTree->GetEntries();
for (Long64_t ievt=0; ievt<nentries;ievt++) {
theTree->GetEntry(ievt);
zzed_hadronic_jetNo = (*zed_hadronic_jetNo)[0];
zzed_hadronic_subjets_E1 = (*zed_hadronic_subjets_E1)[0];
}
...
I get the following segmentation violation error:

The interesting thing is, that when I comment out zzed_hadronic_subjets_E1 = (*zed_hadronic_subjets_E1)[0]; it compiles without any issue. Can somebody explain, why I get this error and why the compilation works, if the latter part of the code is removed (I am a C beginner)? The only difference between the entries of the two branches is, that the zed_hadronic_jetNo refers to a discrete variable (Number of jets per event) while the zed_hadronic_subjets_E1 refers to a continuous variable (energy of one jet).
Thank you very much for your help. 
Best,
Nico
