Not sure what is happening here:

In [1]: import pygeos
In [2]: import numpy as np
In [3]: pygeos.is_missing(np.full((10,), None, dtype=object))
OK
In [4]: pygeos.is_missing(np.empty((10,), dtype=object))
OK
In [5]: pygeos.is_missing(np.empty_like(np.empty((100,)), dtype=object))
Segmentation fault (core dumped)

It doesn't matter which pygeos function you take, the behaviour is consistent: a geometry input constructed with np.empty_like results in a segfault.
