Hi! I added a destructor than "talk" in the python code and
#!/usr/bin/python
import pyinput
import pygeom
import pystate
import pyeqfactory
import pyeigenprobfactory
import pyeigensolver
import pypostprocessing
def deltalk(self):
print type(self).__name__ ," die"
pyinput.Input.__del__ = deltalk
pygeom.ProbGeom1D.__del__ = deltalk
pystate.State1D.__del__ = deltalk
pyeqfactory.EqFactory1D.__del__ = deltalk
pyeigenprobfactory.EigenProbFactory1D.__del__ = deltalk
pyeigensolver.EigenSolver1D.__del__ = deltalk
pypostprocessing.PostProcessing1D.__del__ = deltalk
inp = pyinput.Input("heter1d/1d1g_heter")
geo = pygeom.ProbGeom1D(inp)
state = pystate.State1D(inp, geo);
equation = pyeqfactory.EqFactory1D.New(state)
eigenprob = pyeigenprobfactory.EigenProbFactory1D.New(state, equation)
solver = pyeigensolver.EigenSolver1D(state, eigenprob)
and the python code try to delete the object in a wrong order.
$ python test2_forest.py
EigenSolver1D die
ProbGeom1D die

So this was obviously the problem. I will see if I can change the title of
the question so someone having the same problem can find the answer easily.
Thanks.
