re PR libstdc++/24617 (vector vs __erase_at_end)

Browse source 
2005-12-08  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/stl_vector.h (vector<>::size, resize, capacity,
	operator[]): Avoid troubles with ADL, user defined operators
	and __normal_iterator.
	(_M_erase_at_end): Fix to take a pointer.
	(clear): Adjust call.
	* include/bits/vector.tcc (vector<>::insert(iterator, const
	value_type&), erase(iterator, iterator), operator=(const
	vector<>&), _M_assign_aux(input_iterator_tag), _M_insert_aux,
	_M_fill_insert, _M_range_insert): Likewise.
	(_M_fill_assign, _M_assign_aux(forward_iterator_tag)): Adjust
	_M_erase_at_end call.
	* testsuite/23_containers/vector/types/1.cc: New.
