[pygccxml-development] std::vector<..> iteration error when using two extensions compiled with indexing_suite_v2

[Maik B. <bec...@go...>]

Hello,

I ran into issues when importing two extensions build using indexing_suite_v2.  
My code ran fine, but after I rearranged it, it stopped with:
  RuntimeError: get

The following code reproduces the this error.

ProjA:
{{{ 
#include <vector>
std::vector<double> create_vector_double_A()
{
  std::vector<double> ret;
  for(size_t i = 0; i < 10; i++)
    ret.push_back(i);
  return ret;
}
}}}

ProjB:
{{{
#include <vector>
std::vector<double> create_vector_double_B()
{
  std::vector<double> ret;
  for(size_t i = 0; i < 10; i++)
    ret.push_back(i);
  return ret;
}
}}}

Each project are build with:
  mb = module_builder.module_builder_t( ... , indexing_suite_version=2)

bug.py
{{{
import sys
import os

sys.path.append( os.getcwd() + '/ProjA/build/src')
sys.path.append( os.getcwd() + '/ProjB/build/src')

import ProjA
import ProjB

dv = ProjA.create_vector_double_A()
for d in dv:
    print d
}}}

Running it via
  $ python bug.py
results in
{{{
bug.py:8: RuntimeWarning: to-Python converter for std::vector<double, 
std::allocator<double> > already registered; second conversion method ignored.
  import ProjB

Changing indexing_site_version to 1 makes it work fine.  Is this a known 
limitation or a bug?  

Best,

PS:  full code attached.  Given cmake, boost, gccxml, pygccxml and pyplusplus 
are installed you can run:
$ make -C ProjA
$ make -C ProjB
$ python bug.py
