Bug ID: 22000
Summary: __bit_iterator move_backward looks incorrect
Product: libc++
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
move_backward is implemented as follows for __bit_iterator
template <class _Cp, bool _IsConst>
inline _LIBCPP_INLINE_VISIBILITY
__bit_iterator<_Cp, false>
move_backward(__bit_iterator<_Cp, _IsConst> __first, __bit_iterator<_Cp,
_IsConst> __last, __bit_iterator<_Cp, false> __result)
{
return _VSTD::copy(__first, __last, __result);
}
which copies [__first, __last) into the range beginning at __result where as
move_backward expects the destination range to end at __result.
the obvious correction is:
template <class _Cp, bool _IsConst>
inline _LIBCPP_INLINE_VISIBILITY
__bit_iterator<_Cp, false>
move_backward(__bit_iterator<_Cp, _IsConst> __first, __bit_iterator<_Cp,
_IsConst> __last, __bit_iterator<_Cp, false> __result)
{
return _VSTD::copy_backward(__first, __last, __result);
}
