It patched the bytes object read from the blob, which for a single byte is an immortal singleton, so that the value of that byte was changed in the whole process. Read into a plain buffer instead. The raw read is factored out of read_multiple() into inner_read().

ass_subscript_slice()patched the bytes object read from the blob and wrote it back.For a single byte that object is an immortal singleton, so the value of that byte was changed in the whole process.
It now reads into a plain buffer.
The raw read is factored out of
read_multiple()intoinner_read(), like the existinginner_write().The negative step case (gh-150449, GH-150450) still raises the same
ValueErroras before.
