Thanks. You are probably right - interesting to hear if anyone else has had
the same problem.

I just wanted to make sure that there are no issues regarding size_t and
pointer sizes that could cause this somewhere in the serialization library
(improper initializations, etc.).

I will try the other approaches shortly.

Looks like a compiler bug to me.

You might try the BOOST_CLASS_EXPORT method.

You might try the alternative registration syntax:

ar.template register_type<FloatParameter>(); ...

You might ask microsoft - lol

Other than that I'm not sure what to suggest.
