I'm sorry. I was a bit stressed out yesterday. I recognize that you only
want to help, and I should be more patient.

hi everyone,
i'm having a problem where a boost::python::throw_error_already_set is being
thrown and causes a segfault (linux). unfortunately the error happens from
within python, when reaching the end of an iteration through a vector array,
which was exported using the vector indexing suite.

oh, awesome suggestion, thank you very much! gcc/eclipse outputs that stuff
this way, and
It seems I still have no idea what is going on, and I'm starting to become a
bit desparate. I'm going to post as much as possible about the issue I'm
having.
this is the smallest reproduce for the problem i'm having.
typedef boost::shared_ptr ActorPtr;
class Actor {
public:
ActorPtr parent;
is a tree element with children and a parent pointer. I guess that
assigning ActorPtr(this) appears to construct a new pointer for an object
that is already registered to boost.python.

i am wrapping an abstract class "Actor" which is to be implemented partially
in Python, using a wrapper class that looks like this:
class PyActor : public Actor, public wrapper {
public:
};
the boost.python export code looks like this:
class_("Actor");

thanks for your help, the solution i used was this one:
#include
#include
using namespace boost::python;
tuple py_audio_get_recording_buffer() {
int write_ptr = 0;
std::vector buffer = audio_get_recording_buffer(write_ptr);
return make_tuple(buffer, write_ptr);
}
BOOST_PYTHON_MODUL
i have a function which i wish to wrap, which returns a float buffer and an
integer:
std::vector get_recording_buffer(/* out */ size_t &write_ptr);
alternatively, the function could also just return a pointer to a float
array:
const float *get_recording_buffer(/* out */ size_t &size, /* out */ s
