commit bba4ded3c2f94fe0de6011a6941b135b3cb0370a Author: A. Jiang <de34@live.cn> Date: Thu Jun 12 22:53:41 2025 +0800 [libc++] Fix constructing `bitset` from non-null-terminated arrays (#143691) Unconditional evaluation of `char_traits<_CharT>::length(__str)` is problematic, because it causes UB when `__str` points to a non-null-terminated array. We should only call `length` (currently, in `basic_string_view`'s constructor) when `__n == npos` per [bitset.cons]/8. Drive-by change: Reduction of conditional compilation, given that - both `basic_string_view<_CharT>::size_type` and `basic_string<_CharT>::size_type` must be `size_t`, and thus - both `basic_string_view<_CharT>::npos` and `basic_string<_CharT>::npos` must be `size_t(-1)`. For the type sameness in the standard wording, see: - [string.view.template.general] - [basic.string.general] - [allocator.traits.types]/6 - [default.allocator.general]/1 Fixes #143684 |
