Since you're passing the size into the derived constructor, why don't you just pass it through to the base constructor?

class base { public: base(size_t array_size):size(array_size) { p_array.reset(new unsigned char[size]); } private: size_t size; boost::shared_array<unsigned char> p_array; };

class derived { public: derived(size_t array_size):base(array_size) { } };

Will that work for you?

Exactly. Thank you.
