#1012 [python] duplicate package prefix

[Giuseppe Attardi]

When called with

swig -c++ -python foo.i

on the enclosed file, swig Version 1.3.35 produces code with the wrong types
Parser::Parser::Enumerator and Parser::Parser::Token:

SWIGINTERN PyObject *_wrap_Parser_pipe(PyObject *SWIGUNUSEDPARM(self), PyObject *args) {
PyObject *resultobj = 0;
Parser::Parser *arg1 = (Parser::Parser *) 0 ;
Parser::Parser::Enumerator< Parser::Parser::Token * > *arg2 = 0 ;
Parser::Enumerator< Parser::Token * > result;

Notice that the problem disappears if method pipe() were defined to return void.

This is still reproducible with git master:

  Parser::Parser *arg1 = (Parser::Parser *) 0 ;
  Parser::Parser::Enumerator< Parser::Parser::Token * > *arg2 = 0 ;

[Olly Betts]

Reproducible with git master 29367b31c8202c5cbe72e05927d77004636d6af9.

Running with -debug-module 1 then -debug-module 2 it seems this happens somewhere in between those two stages:
