Hello,
that bug is said to be fixed but I still seem to experience it. I am using a root version compiled from the source: ROOT 5.34/18 (v5-34-18@v5-34-18, Mar 14 2014, 16:29:50 on linuxx8664gcc). My sytem is Release 12.04 (precise) 64-bit, Kernel Linux 3.2.0-61-generic, GNOME 3.4.2. The code worked with root 5.28.00h
Here the part of the code it crashes:
void
Overlap::AddTreesToFiles(TString inputdir){
TString ovstr = "_ovcode";
TString rmstr = "_ovremoved";
for( int imode = 0; imode < Modes::nModes; imode++ ){
//open files for modifications
TString fname = inputdir + Modes::ModeName(imode) + ".root";
TFile f(fname, "UPDATE");
if( !f.IsOpen() ){
cout << "WARNING: file not found skipping it! fname = " << fname << endl;
continue;
}
for(int ipi = 0; ipi < Pions::AllPi; ipi++){
//debug: skip for now to save time
//if( ipi == 0 ){
// cout << "skipping npi = 0 " << endl;
// continue;
//}
TString treename = Modes::ModeName( imode ) + Pions::GetID( ipi ) + "_" + exttree;
//remove the old overlap trees if present
if( f.Get( treename + ovstr ) || f.Get( treename + rmstr ) ){
cout << "WARNING: found old overlap trees in the file for " << treename << endl;
cout << "will remove those now!" << endl;
f.Delete( treename + ovstr + ";*");
f.Delete( treename + rmstr + ";*");
}
TTree * t = (TTree*)f.Get( treename );
if( !t ){
cout << "WARNING: tree not found: " << treename << " skipping this sample" << endl;
continue;
}
//get the tree with overlap codes
TTree * ovt = GetOverlapTree( t, treename + ovstr, (Pions::nPi)ipi, (Modes::Mode)imode);
f.cd();
ovt->Write();
t->AddFriend( ovt );
int rmcode = GetRemCode( (Pions::nPi)ipi, (Modes::Mode)imode );
TString cut = "0==(ovcode&";
cut += rmcode;
cut += ")";
//==============>This is the line where it crashes:
TTree * rmt = t->CopyTree(cut);
rmt->SetName( treename + rmstr );
f.cd();
rmt->Write();
}//end ipi
f.Close();
}//end imode
}
I can not provide a small standalone example.
