This has arisen in connection with an issue in Boost.Flyweight:

https://svn.boost.org/trac/boost/ticket/6382

intermodule_singleton is an internal component of Boost.Interprocess
(besides being used by Boost.Flyweight with kind permission from
Ion) so I guess there's a way to expose this problem also from the
public interface of Boost.Interprocess.
