   I am not familiar with the trunk tests.  However XL 10.1.0.3 AIX is the latest C++ compiler. 

  http://www.boost.org/development/tests/trunk/developer/serialization_.html

  From your reply your saying that this is a compiler bug 

  Export facility depends upon non-portable C++ features.  Not all compilers support these features.

  Do you know if any defect report has been raised ?

  I believe that the development team for this compiler is aware of this situation.

  Is there any workaround that stops the compiler doing these optimisation.

  Consider using explicity type registration in the archive.  This is totally portable to all C++ compilers.

  If not is there possibility of changing the serialization code ?

  I don't believe that it's possible.  I don't have the compiler.  And I couldn't justifty the time in any case
