> Comparing a string array with a string scalar works:
> {code:java}
> In [1]: import pyarrow.compute as pc
> In [2]: pc.equal(pa.array(["a", None, "b"]), pa.scalar("a", type="string"))
> Out[2]:
> <pyarrow.lib.BooleanArray object at 0x7f38d56e23a8>
> [
> true,
> null,
> false
> ]
> {code}
> but if the scalar is a null (from the proper string type), it crashes:
> {code:java}
> In [4]: pc.equal(pa.array(["a", None, "b"]), pa.scalar(None, type="string"))
> Segmentation fault (core dumped)
> {code}
> (and not even debug messages ..)
