c++/8285: default arg doesn't work in vector

Thanks nathan, the vector constructor use the copy
constructor to create the other n-1 objects of the
vector when called with vector<T>(n) but it created an
instance for each element for vector<T>(n, v).

i saw one object was created, i just couldn't figure
out why the rest weren't.  

Thanks, you r the man.  but Nathan, i can't remember
reading about this in the C++ Programming Language. 
Is this how it should work?  I know, my class should
have a copy constructor if it has pointer members,  i
just didn't think the vector would use it.  

Thanks again.
