New submission from Amaury Forgeot d'Arc <[email protected]>:
This crashes on python 3.3::
class S(ctypes.Structure):
_fields_ = [(b'x', ctypes.c_int)]
This also crashes on python 2.7::
class S(ctypes.Structure):
_fields_ = [(u'x\xe9', ctypes.c_int)]
The cause is the same: in Modules/_ctypes/stgdict.c, the assignment
fieldname = _PyUnicode_AsString(name);
does not check for errors.
