10834,ptr_array cannot be used with boost::nullable<T> as type parameter,florian.schmid1978@…,Thorsten Ottosen,"The copy constructor of ptr_array uses operator[] to access the elements of the ptr_array to copy.[[BR]]
Problem one: It is not save to call ptr_array[i] if element i is null.[[BR]]
Problem two: Operator[] returns a reference to remove_nullable<T>::type.
The address of this object is then casted to const T*, which fails with
compilation error C2664 if T=nullable<X>, because X* cannot be casted to nullable<X>*.

Reproduction: compile attached test.cpp[[BR]]
Possible fix: see attached patch[[BR]]
