I read that as saying that the code in the mail at the start of this thread is perfectly safe, don't you?
Well, we also have:
template<class _Traits>
class _Tree
{
const_iterator find(const key_type& _Keyval) const
{ // find an element in nonmutable sequence that matches
_Keyval
const_iterator _Where = lower_bound(_Keyval);
return (_Where == end() || this->comp(_Keyval,
_Key(_Where._Mynode()))
? end() : _Where);
}
}The find method might return a temporary const_iterator, but I can't tell whether this is a problem or not.
