> Commit 8385bba added code which thoroughly compares protobuf messages, however one of the changes looks like:
> {code}
>   return left.task_id() == right.task_id(); // This semicolon shouldn't be here.
>     left.state() == right.state() &&
>     left.data() == right.data() &&
>     left.message() == right.message() &&
>     left.slave_id() == right.slave_id() &&
>     left.timestamp() == right.timestamp() &&
>     left.executor_id() == right.executor_id() &&
>     left.healthy() == right.healthy() &&
>     left.source() == right.source() &&
>     left.reason() == right.reason() &&
>     left.uuid() == right.uuid();
> {code}
> which results to clang build's failing with "expression result unused." Not to mention the given code has a bug in itself.
