Unless you've also wrapped std::vector<int>, I don't think your
getPosicion() wrapper will work in Python (it should throw an exception
when you call it).
And by the way, you probably want "return_internal_reference<>" instead
of "reference_existing_object" to be a little safer - that tells Python
your MyClass instance owns the vector, rather than stating "I promise
this reference will stay valid".

I don't really understand what you're doing here. Where is getObj()
defined, and what does it do? I gather that your "main program" is
written in C++, not Python - are you embedding?
I'm not sure the std::vector stuff above is related to your problem, but
without knowing more I can't say.
