[New-bugs-announce] [issue14563] Segmentation fault on ctypes.Structure subclass with byte string field names
report at bugs.python.org

New submission from aliles <aaron.iles at gmail.com>:
Python 3.2 will exit with a segmentation fault if a byte string is used as a field name in a subclass of ctypes.Structure.
Python 3.2.2 (default, Dec 18 2011, 18:56:20)
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> class Point(ctypes.Structure):
... _fields_ = ((b'x', ctypes.c_int), (b'y', ctypes.c_int))
Segmentation fault: 11
This also occurs if None or an int is used as the field name.
I would expect that a TypeError exception would be raised if an attempt is made to use an invalid type for the field name.
