[Swig-user] Python, iterate on vector of enum (segfault)

[David F. <dav...@gm...>]

Hi dear swig users,

I get a segmentation fault when trying to iterate in Python on C++
vector of enum (swig 2.0.4).

Is it a bug in Swig or did I made something wrong?

Thanks for reading,
Best,

David.



An example to reproduce the segmentation fault is in attachment, here are the
main files:


#file: vec_enum.hpp
class EnumVector
{

    public:

        EnumVector();
        ~EnumVector();

        enum foobarbaz{foo,bar,baz};

        vector<foobarbaz> spam;
        void fill_spam();
        void print_spam();
};


#file: vec_enum.i
%module vec_enum

%{
#define SWIG_FILE_WITH_INIT
#include "vec_enum.hpp"
%}

%include "std_vector.i"

namespace std {
  %template(vector_foobarbaz) vector<EnumVector::foobarbaz>;
}

%include "vec_enum.hpp"

#main.py
import vec_enum

ev = vec_enum.EnumVector()
ev.fill_spam()

print ev.spam[0] # ok
print ev.spam[1] # ok
print ev.spam[2] # ok

for e in ev.spam:
    print e # segmentation fault
