Summary: Ref count...

Initial Comment:
Consider the following example:

t01.i:
%module t01
%{
# include <iostream>
# include "t01.hh"
# define TRACE(arg) std::cout << __FILE__ << "(" << __LINE__ << ") : " 
<< arg << std::endl
%}

%feature("ref")   Pouet "TRACE(\"up ref\");"
%feature("unref") Pouet "TRACE(\"down ref\");"

%include "t01.hh"

t01.hh:
#ifndef T01_HH__
#define T01_HH__

struct Pouet
{
  int a;
};

#endif

t.php:
<?php
include("t01.php");
$p = new Pouet();
?>

I compile with :
$ swig -php4 -c++ -Wall t01.i
$ g++ t01_wrap.cpp -shared -I. -I/usr/include/php4 -I/usr/include/php4/main -I/usr/include/php4/TSRM -I/usr/include/php4/Zend -g -o t01.so

And when I run it :
PHP Warning:  mime_magic: type regex            BEGIN[[:space:]]*[{]    
application/x-awk invalid in Unknown on line 0
t01_wrap.cpp(1094) : down ref

My problem is why there is only unref but not ref and unref. I do its test in perl5 and there is ref and unref.

And I think I find the bug in swig source (version 1.3.31) (see my patch).

And after its patch we can see :
PHP Warning:  mime_magic: type regex            BEGIN[[:space:]]*[{]    application/x-awk invalid in Unknown on line 0
t01_wrap.cpp(1076) : up ref
t01_wrap.cpp(1095) : down ref
(like perl)
