It sounds to me like you were relying on an implementation dependency.
My copy of "C++ Standard Library" by Josuttis just says that both of
these will remove all the elements of the vector.  AFAIK, the standard
makes no requirements about allocation/deallocation behavior for these
operations, but I would expect both to potentially deallocate memory
when I delete the whole vector.  If you want to clear the vector
without changing its allocation, you should do vector::resize(0) IMO.
