URL: https://github.com/apache/arrow/pull/1418#issuecomment-352523219
> These are probably due to liborc symbols not being hidden in the generated
shared libraries. If you like I can make a PR to your PR to fix this.
That'd be useful, I don't fully understand what the `symbols.map` file is
doing.
> In general, we follow the Google C++ styleguide in Arrow. One of the
specialities of it is that unsigned integers are not used.
I've removed the use of unsigned integers in several (but not all) places.
These were used to match the api of `liborc`, which makes heavy use of them. I
could remove them completely, but would need to explicitly check range and cast
when interacting with `liborc` then.
