TTree with TClonesArray

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.
