I am not a language lawyer so I am not going to say anything about the
behaviour you are getting.  But I have a suggestion for what you are trying
to do.

How about writing a public member function for class Two that calls the
class One constructor and use that member function instead.
Some thing similar to this:
-----------------
#include <iostream.h>

class One
{
    friend class Two;
    private:
        One(){ cout << "constructing class One instance\n";}
};

class Two
{
    public:
        Two(){ cout << "constructing class Two instance\n";}
        One *make_one(){return new One();}
};

main()
{
    One *ione;
    Two *itwo;

    // instantiating itwo of class Two
    itwo = new Two();
    // instantiatin ione of class one by calling Two::make_one()
    ione = itwo->make_one();
} 
-------------------
output of the above:

constructing class Two instance
constructing class One instance

I am not sure this is what you want to do but...
