Dear Rene
I found the shortes way to reproduc the problem which has nothink to do with
my classes.
This is test1.cpp macro
{
TFile * file = new
TFile("/home/margar/TileData/2004/ntuple_870_2100033.root" , "READ"); TTree
* tree = (TTree *) file->Get("TileRec/h1000");
tree->AddFriend("TB/tree");
tree->Draw("SC1");
tree->Draw("Eh_EMB[0]"); //Eh_EMB[0] belongs to TB/tree
gROOT->ProcessLine(".q");
}
if I comment tree->AddFriend("TB/tree") and tree->Draw("Eh_EMB[0]") then
everythink is fine the same root file could be found on castor
/castor/cern.ch/user/v/vgiangio/RecExTB-00-00-41/ntup/ntuple_870_2100033.roo

this is output of gdb and root
