Dear Roman,
thank you very much for the suggested workaround. Could you answer the additional questions below?

Yes, with your suggestion I can at least work with the code.
But would you mind mentioning the other alternatives? My aim is to construct the class like the "t=testmodule.Test("Hello")" above.
I was not able to use the suggested "create_*" functions as fake constructors "test.add_fake_constructors( mb.calldefs( 'create_test_from_char' ) )". Do they have to return an auto_ptr<Test> for this purpose?
Thank you
Werner
