So what am I missing here?

You are missing a copy constructor. Even though my_test() takes arguments by reference, Boost.Bind binds them by value and since you have scoped_array you need to provide a copy constructor (in addition to operator=) yourself.

Thanks, that worked.

Or, you can bind by reference:

boost::bind( ... , ref(obj3), ... )

This didn't: the shared_arrays my object contained 10 objects when they were created but only 3 after being passed to the function. Not to worry anyhow, as the "proper" method of supplying and copy constructor and an assignment operator worked fine.
