Hi Robert,
 
Maybe you've missed my previous reply, see @ Thu, 2 Feb 2006. So I
re-post it 
 
Thanks to handle my request; I've looked the source directory "test" and
"examples" of boost::serialization ver#1.33.1 and I didn't find the test
that you've pointed in your reply.
 
What's the name of the test demonstrating separate compilation?
Do you have tested my source code sends with my previous post?

The figure hereafter describes the relationships between LibA, LibB and
EXE application:

                      |       LibA      |                              |
LibB       |

                                               \                       /

                                                  Exe Application
 
We have to face to an assert in debug mode generate by the file
boost::serialization::extended_type_info.cpp, line#71. This assert
happens during the instance serialization of class libB:B. 
 
Recently, there are some posts on this subject, but I would like to
known how I can deal with this assert? Is it possible to avoid it by a
code organisation? Is it possible to comment this assert?
 
To have a concrete answer, I have joined my complete VC++7.1 project. 
 
Thanks in advance for your help.
