When std::deque runs out of allocation, it allocates a new memory  
chunk for extension without keeping the old one intact, thus avoiding  
invoking copy constructors, using C++ class interface capability to  
paste it together transparently. The class std::vector is just a  
traditional array, which copies the old data over to a larger chunk.  
Thus, it works like the current C stacks that Bison uses.
