The Gandiva failures seem unrelated.

[lidavidm]

I'll file an issue for Gandiva since it appears on master. It seems to have started with b31dd51 even though that looks unrelated; since the failing builds use unity builds it seems something about it shifted how the unity build combines files.

Thanks. I'll file a PR for it.

[lidavidm]

I filed ARROW-15028

[pitrou]

I filed #11905 -- hopefully it'll pass.

[pitrou]

The Gandiva fix was merged, it's in git master now.

[lidavidm]

Looks like this passes once rebased, thanks for fixing the issue.
