2002-12-26 Phil Edwards <pme@gcc.gnu.org> * include/std/std_bitset.h (_Base_bitset::_M_do_left_shift, _Base_bitset::_M_do_right_shift): Expect a non-zero shift. (bitset::operator<<=, bitset::operator>>=): When shifting more bits than are in the bitset, zero memory rather than segfault. (operator>>(basic_istream,bitset): Only call setstate once, after all work has been done. * testsuite/23_containers/bitset_members.cc (test03): New test. * testsuite/23_containers/bitset_shift.cc (test02): New test.
