New submission from Eric Wieser <wieser.e...@gmail.com>:
This behavior is pretty surprising:
```python
import ctypes
class Simple(ctypes.Structure):
_fields_ = [
('a', ctypes.c_uint8),
('b', ctypes.c_uint8),
]
class Bitfields(ctypes.Structure):
_fields_ = [
('a', ctypes.c_uint8, 8),
('b', ctypes.c_uint8, 8),
]
print(Simple.b.size) # 1
print(Bitfields.b.size) # 262148
```
The docstring for this field, from `help(type(Bitfields.b).size)`, is:
> Help on getset descriptor _ctypes.CField.size:
>
> size
> size in bytes of this field
So either the behavior or the docstring needs to change.
