[boost] [serialization] BOOST_CLASS_EXPORT regression?

Hello,
I've have a header file like this:

   namespace lvk { namespace nm_model { namespace runtime {
         class IntTraceItem {};
   }}}

  BOOST_CLASS_EXPORT(lvk::nm_model::runtime::IntTraceItem);

The header is included in two files. It used to work before, but I've just 
updated to CVS state of the serialization lib, and get:

src/runtime/bin/gcc/debug/threading-multi/TraceArbiter.o(.bss+0x0):src/runtime/TraceArbiter.cpp:16: 
multiple definition of 
`boost::archive::detail::guid_initializer<lvk::nm_model::runtime::IntTraceItem>::instance'
src/runtime/bin/gcc/debug/threading-multi/Trace.o(.bss+0x0):src/runtime/Trace.cpp:21: 
first defined here

I attach the testcase. When I run

   g++ -I ~/Work/boost-rc s1.cpp s2.cpp 

the first error is about duplicate symbols.

Am I doing something wrong or is this a regression?
