When an extension module is compiled with CPython3.4, the nb_matrix_multiply slot is not filled, and no memory is allocated for it.
If the extension module is imported by CPython3.5, nb_matrix_multiply contains garbage and segfaults the interpreter.

In Python 2.7 there are flags like Py_TPFLAGS_HAVE_INDEX to gate the access  to recently added slots. I think Python3.5 should have a similar one.
