Python : segmentation fault

[nimitsis]

Hello everyone
I try to extend Python using a simple C wrapped module . This module includes embedded python code and it is product of Swig . The corresponding files follows :

//main.c
#include "Python.h"
#include <stdio.h>
 
int main()
{
    Py_Initialize();
    PyRun_SimpleString("execfile('simple.py') \n");
    Py_Finalize();
    return 0;
}

//simple.py
 
print " Hello, everyone"

/* example.i */
 
%module example
 
%{
#include "Python.h"
int main();
%}
#include "Python.h"
int main();

//extend.py
 
import _example
_example.main()

The file main.c embeds python , which only execute the file simple.py. The example.i is the interface file , which is used from Swig to generate the desirable module _example.so . This module called from script python file, extend.py for execution.

To do those things from Linux command prompt I execute the following commands:

$ swig -python example.i
$gcc -c main.c example_wrap.c -Dmain=oldmain -I/usr/include/python2.5
$ld -shared example_wrap.o main.o -o _example.so
$python extend.py
Hello everyone
Segmentation fault (core dumped)

Why does the last message appear ? Swig supports wrapping of embedded with python , C code? Do you have any idea how to solve this problem ?I will appreciate any answers .
Thanks a lot

The swig users mail list is actually quite good.
