Hello, I'm having troubles with TTree::Fill() crashing ROOT with the following example. I've noticed that if the split option in tree->Branch is set to 0, things do run. But I'm partial to having my tree automatically branched if possible. I'm I doing something wrong here? Thanks again for all you help.
