[C++-sig] Problem with custom lvalue converter

[Tore Birkeland]

Hi

I'm using boost::python to create a wrapper for my quantum mechanics
propagator, and I've run into the following problem:

When i create a custom lvalue converter, and instance a new c++ class
from within the construct() method (as described in the FAQ), the
destructor for that object is called twice! Can someone tell me what I
am doing wrong, and how to avoid it?

I have attached c++ and .py files that reproduce the problem. When
destructorproblem.py is run, i get the following output:

> python destructorproblem.py
Constructing A
Got A
Destructing A
Destructing A

best regards,
Tore Birkeland
