Thanks for the tip. I re-activated the trap... and indeed i found some
serialization code that was in several DLLs. However, even though I fixed
the problems I found, the trap did spring up again at code that I know is
not duplicated across DLLs. 
I still think that the singleton creation is not only a side-effect of
exporting a type (using BOOST_CLASS_EXPORT_IMPLEMENT) but also happens when
using the serialization for a given type ( à la "ar & t"). It is a quite
complex behavior, I don't understand it completely because from my
understanding I expected a lot more trapping to happen.
