The problems are associated with:
     boost 1.42
     serialization
     v11.1 c++ compiler ( newly released )

What I found was the in debug everything was ok, all my test ran, however
in release mode, the boost serialization crashed. So I want to experiment with
different optimisation, to to see what affect it had. However I struggled to achieve this.
