New submission from Jakub Wilk:
If you initialize array with another empty array, then this code runs:
memcpy(self->ob_item, other->ob_item, len * other->ob_descr->itemsize);
But self->ob_item and other->ob_item are NULL in such case.
Passing null pointer to memcpy() is undefined behavior even when length is 0.
