On Debian x64 stable with Python 2.7 and 3.4, the following causes a segmentation fault:

from ctypes import string_at
string_at(None)

On Windows 64-bit with Python 2.7 it raises WindowsError and Python 3.3 raises OSError, both showing a message "access violation reading 0x0000000000000000", but it does not crash.

The above behavior was found when reading a result from a C API that can be either a zero-terminated string or NULL.
