I do not want python to manage instance of AAA. I specified AAA* 
as second argument.

And they are not constructible from python

This I am not sure what it has to do with my question. 
I am not setting python global var.

But!

adding boost::ref to the 

obj.attr( "aaa" ) = boost::ref( s_global );

did resolve the issue, though I am quite confused  why it is required.
