The overflow is in `SliceBytesTransform::MaxCodeunits` (scalar_string_ascii.cc on main): `(opt.stop - opt.start + opt.step - 1) / opt.step` with the default `stop` of `numeric_limits<int64_t>::max()` wraps negative when `start > 0`, and that negative bound is what becomes "Negative buffer resize". #36575 fixed the same expression for `utf8_slice_codeunits`; the byte-slice transform still has the original form. -- This is an automated message from the Apache Git Service.
