Multiple inheritance error with __slots__

When creating a Python class from two base classes, one of which is a Python class that uses __slots__ and the other a pybind11 generated class, I get the Python error:

TypeError: multiple bases have instance lay-out conflict

There is no error if the Python class does not use __slots__. Below is code to reproduce. I am using the master branch of pybind11. Error is seen with Python 2.7 and Python 3.6.

import example

class MyClass0(object):
    __slots__ = ["name"]  # Comment this line to avoid error
    def __init__(self, name):
        self.name = name

class TestClass(MyClass0, example.Base0):
    def __init__(self):
        pass

#include <pybind11/pybind11.h>
namespace py = pybind11;

struct Base0 { };

PYBIND11_MODULE(example, m)
{
  py::class_<Base0>(m, "Base0");
}

Start with the Python reproducer defining MyClass0 with slots and TestClass inheriting from MyClass0 and example.Base0, then build and run the shown pybind11 module containing Base0. Compare the result with slots removed; the issue is resolved when the reported multiple-bases instance-layout conflict is addressed for the supplied case.
