Eryk Sun added the comment: In older versions of ctypes, before it was added to the standard library, the underlying length field was a C int, and CArrayType_new used the PyInt_AS_LONG macro. ctypes was added to the standard library in 2.5, by which time the length field is Py_ssize_t, but CArrayType_new still used the PyInt_AS_LONG macro. That's still the case in 2.7. Python 3 changed this to call PyLong_AsLongAndOverflow, but apparently Christian Heimes didn't consider fixing this properly to use Py_ssize_t:
