Strange errors with TTrees and TMultiLayerPerceptrons

Hello!
I've been working with the TMultiLayerPerceptron class from ROOT and have encoutnered some strange behaviours that none of my collegues and I could understand:
I filled a ROOT tree in a function, returned it to the main program and then gave it as parameter to another function where I want to run the MLP over it. Here the program crashes with a stack violation even though the tree is still prior to starting the MLP in that function. When I put the MLP code in the same function that fills the tree, everything works fine.

The small sample code and root tree can be found here: http://www-ekp.physik.uni-karlsruhe.de/~schiefer/mlp.root http://www-ekp.physik.uni-karlsruhe.de/~schiefer/mlp.cc
