ACE requires you to use multithreading in most cases. I seriously
doubt that this will be seen as a bug by anybody you've reported to,
as this is just how ACE works.

In this case, sp_counted_base is doing the right thing, as it sees
that it needs to be threadsafe.

I would strongly recommend that you ensure that you use the same
compilation flags and defines to build your software as you did when
building ACE, otherwise you may just end up with different versions of
the same class all over the place.
