New submission from Anthony LaTorre: I get a segfault when trying to cast a string to a structure. >>> import ctypes >>> class Struct(ctypes.Structure): ... _fields_ = [('a', ctypes.c_uint32)] ... >>> s = '0'*100 >>> ctypes.cast(s,Struct) Segmentation fault
The docs (https://docs.python.org/2/library/ctypes.html#ctypes.cast) say that `obj` "must be an object that can be interpreted as a pointer", so I assume this should return the same exception you get when trying to cast a list: >>> ctypes.cast(range(10),Struct) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.4/ctypes/__init__.py", line 488, in cast return _cast(obj, obj, typ) ctypes.ArgumentError: argument 1: <class 'TypeError'>: wrong type ---------- messages: 223062 nosy: Anthony.LaTorre priority: normal severity: normal status: open title: segfault in ctypes.cast type: crash versions: Python 2.7, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21983> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
