[jira] [Updated] (ARROW-10578) [C++] Comparison kernels crashing
for string array with null string scalar
[ https://issues.apache.org/jira/browse/ARROW-10578?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kirill Lykov updated ARROW-10578:
---------------------------------
Description:
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 ..)
