> [C++][Plasma] TEST(PlasmaSerialization, GetReply) is failing

> Key: ARROW-5194

> Project: Apache Arrow
> Issue Type: Test
> Components: C++ - Plasma
> Affects Versions: 0.13.0
> Reporter: Guillaume Horel
> Assignee: Guillaume Horel
> Priority: Critical
> Labels: pull-request-available

> I believe the
> [assertions|https://github.com/apache/arrow/blob/master/cpp/src/plasma/test/serialization_tests.cc#L191]
> here are incorrect. You can't use memcmp to compare structs
> On my machine (64bits linux) int are 4 bytes, but the struct fields are 8
> bytes aligned, so this line fails:
> ASSERT_EQ(memcmp(&plasma_objects[object_ids[0]], &plasma_objects_return[0],
> sizeof(PlasmaObject)),
> 0);
> even though the struct contents are the same.
