Hi, 
I dived into the source code of the library and found a workaround to allocate 
such objects. Unfortunately, I had to specialize a class in the Detail 
namespace. With a hook in the pointer_iserializer and pointer_oserializer it 
would have been very easy to implement this. I don't know whether there are 
other cases where such an extension could be useful. Just wanted to let you 
know that i found some solution. (see attachment)

Regards and thanks,
Roland
