I encountered a similar problem when trying to use another vector  
implementation (similar to auto_buffer in the review queue) with  
dynamic_bitset.
all of these problems could be solved if dynamic_bitset was changed  
into a container adapter similar to std::stack and leave the  
underlying container to the user.
