New submission from Louie Lu:
For this situation, check boundary error message didn't correctly show out.
>>> import struct
>>> import ctypes
>>> byte_list = ctypes.create_string_buffer(1)
>>> struct.pack_into('b', byte_list, 5, 1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
struct.error: pack_into requires a buffer of at least 1 bytes
Since offset is setting at 5, it should at least need `offset + soself->s_size`
bytes to store it.
