std::string::reserve vs std::vector::reserve

[Peter Soetens]

Hi,

I do not have the Standard, but the "C++ Programming Language" by BS states 
that both string reserve and operator= behave 'like' vector's. Well, in GCC 
2.95, 3.2, 3.3,3.4 and 4.0, it doesn't (so I'm probably wrong...).

A vector keeps its reserved capacity after an assignment, a string doesn't. 

I know this is because of the COW implementation. In fact, the string gets the 
capacity of the original... How does the Standard define the correct 
behaviour ? Will one day vector behave likewise ?

A Test program is in attachment.
