Summary: vector of enums isn't passed correctly

Initial Comment:
I have defined an enum Test::NUMBER and a method with a parameter of type vector<Test::NUMBER>. I have
added an include in the swig file for "std_vector.i" and added a %template directive that should handle
the vector. 

Instead, I get a segfault coming from _wrap_Test_test_enum_vector in the wrapper file. It seems to fail
when calling push_back() on the instance of std::vector<Test::NUMBER > (line 3045). 

The method is called fine if the parameter is std::vector<int> or just Test::Number.

Incidentally, the included code is a stripped-down a larger project wherein I originally saw the bug.
However, since I was calling the method in a different context, the segfault was not occuring, rather the
ENUM values were changed. I have not been able to do a simple repro of this.

If you would like to see the code from the bigger project, I can provide that too, since it is an open-source project.

Version info:

ruby 1.8.5
Windows XP SP 2.
Swig 1.3.31
Microsoft Visual C++ 2005.

Note that if you want to use the VC++ project, paths must be changed in the "Debugging" and "Build Swig"
properties and

This file seems to not have been created with the latest release of swig
on SVN, but the much older swig1.31.

Can you download the latest SVN, compile it and try it?  Compilation on
windows means you will need to install MSYS and autotools for it (this is
kind of a pain, I'll admit -- until there's a proper formal release).

I'm attaching a simple example that works for that version.

--------
%module enumvector

%include std_vector.i

%inline {
  namespace test {

   enum Number {
     One,
     Two,
     Three
   };

  }

}

// this should work, but it is broken as test::Number is interpreted as
// a class and there's no type_info() for it (I'll see if this can be
fixed easily):
//
// %template(EnumVector)  std::vector< test::Number >;

%template(EnumVector)  std::vector< int >;
