That's not much help, is it!?

Well, let's see.  I think you can do this analysis yourself, FWIW:

/net/legless/scratch1/rwgk/hot/boost/boost/python/object/make_instance.hpp:63:
error: request for member M-CM-"M-bM-^BM-,M-KM-^\get_class_objectM-CM-"M-bM-^B
M-,M-bM-^DM-" in
M-CM-"M-bM-^BM-,M-KM-^\boost::python::converter::detail::registered_base<const v
olatile
Y&>::convertersM-CM-"M-bM-^BM-,M-bM-^DM-", which is of non-class type M-CM-"M-b
M-^BM-,M-KM-^\const
boost::python::converter::registration&M-CM-"M-bM-^BM-,M-bM-^DM-"

It seems to be claiming that the static

   registration const&

member named "converters" of

  registered_base<Y const volatile&>

Doesn't have class type.  Clearly wrong.  I mean, it's a reference to an
object of class type, but for all purposes other than initialization you
can do the same things with that as you can do with a class instance.

GCC bug?
