Sure, I agree. I was just trying to provide more info.

In the tests I am rrunning, each boost unit test is linked with its
own main, so no two serialization tests run together. One of those
tests fails.

All of the individual tests are single threaded (although for build
reasons they are linked with the mt libraries). That is, no test
creates any additional threads.

I've done this and the destructor is called 15 times. It isn't
obvious to me if this is unexpected (since this could be the base
class of a hierarchy of singletons).
Each time it is invoked on a different instance of this. Breakpoints
and stack traces are at the end of this message. In the final call to
~singleton the object address is identical to the address of the
~extended_type_info object in the seg fault stack trace.
Note that only the primary thread is ever created. Also, this unit
test contains only a single top-level call to the serialization code.
Of course, there are nested objects being serialized.
Hope this helps. Let me know if there are more tests I can run.
Thanks,
