Hi Gabriel,
  Thanks for your response. I can modify my code to call
Py_IsInitialized which I didn't know before and this works well. The
problem is that I did not own the process which calls Py_Initialize
and Py_Finalize. I'm able to call Py_Initialize correctly but I can't
call Py_Finalize so this is not perfect.

At least I have a temporary solution which is not too bad.
Thanks,
Jerome
