[ROOT] TClonesArray / TRefArray

Hi Rooters!

I am trying to create a tree that contains as subbranches two
TClonesArrays, say *Tracks and *Hits, where Hits contains all hits in
the detectors, and tracks contains all tracks found (similar to the
Event example).

Now I would like that each track keeps a reference to its hits. I was
trying to add a TRefArray of *Hits to each track, which seems ok when I
am creating the tree. Reading back the tree, however, I get segmentation
violations. Is it possible at all to nest TClonesArrays and TRefArrays
in a tree, or did I miss something else?

Thanks for your help,

	Bernhard
