[Vincent Pelletier]

New submission from Vincent Pelletier <plr.vincent at gmail.com>:

pypy1.9:
>>>> import ctypes
>>>> class Foo(ctypes.Structure):
....   _fields_ = (('user_data', ctypes.py_object), )
.... 
>>>> a = Foo()
>>>> a.user_data = None
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/vincent/git/ITI1480A-linux/pypy-1.9/lib_pypy/_ctypes/structure.py", line 105, in __set__
    cobj = fieldtype.from_param(value)
  File "/home/vincent/git/ITI1480A-linux/pypy-1.9/lib_pypy/_ctypes/primitive.py", line 287, in from_param
    return super(SimpleType, self).from_param(value)
  File "/home/vincent/git/ITI1480A-linux/pypy-1.9/lib_pypy/_ctypes/basics.py", line 46, in from_param
    self.__name__, type(value).__name__))
TypeError: expected py_object instance instead of NoneType

cpython 2.7.3:
>>> import ctypes
>>> class Foo(ctypes.Structure):
...   _fields_ = (('user_data', ctypes.py_object), )
... 
>>> a = Foo()
>>> a.user_data = None
