Hi

I've tried to set up a small example that can reproduce the problem, however I cannot seem to succeed...

One thing is sure, the crash is due to the BSL and the base_object thing, because if I change this only thing, the program goes from running perfectly to crashing at launch. 

Note that it is not really a problem of a class having multiple parents (this could happen if for example you use multiple inheritance). It is a problem of a class "switching parents".

Note that there is a test test_..._mi which tests serialization with classes
which have multiple parents.  So I would hope that this wouldn't be
a problem. But you never know
