Using the C-API, the inplace_pow numbermethod is always called with the third argument pointing to an invalid address. The reason is likely that self.__ipow__ only takes one argument, resulting in a binaryfunc (self, arg), though inplace_pow is a ternaryfunc. When trying to use the third argument in any way, Python crashes. The third arg should be nonexistent, NULL or Py_None.
