> [Plasma][C++] Serialization tests resort to memcpy to check equality
> --------------------------------------------------------------------
>
> Key: ARROW-5036
> URL: https://issues.apache.org/jira/browse/ARROW-5036
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++ - Plasma
> Reporter: Francois Saint-Jacques
> Priority: Major

> {code:bash}
> 1:
> /tmp/arrow-0.13.0.Q4czW/apache-arrow-0.13.0/cpp/src/plasma/test/serialization_tests.cc:193:
> Failure
> 1: Expected equality of these values:
> 1: memcmp(&plasma_objects[object_ids[0]], &plasma_objects_return[0],
> sizeof(PlasmaObject))
> 1: Which is: 45
> 1: 0
> 1: [ FAILED ] PlasmaSerialization.GetReply (0 ms)
> {code}
> The source of the problem is the random_plasma_object stack allocated object.
> As a fix, I propose that PlasmaObject implements the `operator==` method and
> drops the memcpy equality check.
