1460,"Python classes with multiple bases are convertible only to the first class in the lists (even if super(classname, self).__init__() is called)",Piotr Jaroszyński <p.jaroszynski@…>,Dave Abrahams,"first reported here: http://mail.python.org/pipermail/c++-sig/2007-October/012926.html

{{{
C++:
#include <boost/python.hpp>

namespace bp = boost::python;

struct A { };
struct B { };

void test_A(const A &) { }
void test_B(const B &) { }

BOOST_PYTHON_MODULE(multiple_inheritance)
{
    bp::def(""test_A"", &test_A);
    bp::def(""test_B"", &test_B);

    bp::class_<A>(""A"", bp::init<>());
    bp::class_<B>(""B"", bp::init<>());
}

Python:
class C(A, B):
    pass

test_A(C())
test_B(C())

And I get:
Traceback (most recent call last):
  File ""./multiple_inheritance.py"", line 10, in <module>
    test_B(C())
Boost.Python.ArgumentError: Python argument types in
    multiple_inheritance.test_B(C)

I will try to figure it out once I am done with the exceptions.",Bugs,reopened,To Be Determined,python USE GITHUB,Boost 1.34.1,Problem,,,
