-----------------------------------
Summary: [C++] Valgrind reports leaks from protobuf allocated
memory in substrait tests
Key: ARROW-18070
URL: https://issues.apache.org/jira/browse/ARROW-18070
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Weston Pace
See
https://dev.azure.com/ursacomputing/crossbow/_build/results?buildId=37514&view=logs&j=0da5d1d9-276d-5173-c4c4-9d4d4ed14fdb&t=d9b15392-e4ce-5e4c-0c8c-b69645229181&l=5635
for an example.
It's unclear to me at the moment if these are valid leaks or something we need
to suppress.
It's also possible they could be prevented by running
{{google::protobuf::ShutdownProtobufLibrary()}} at test shutdown.
Either way, it would be good to validate these are not legitimate issues and
prevent them in some way.
