Uhm, that's bad, the rollup (#151129) just failed on the same thing. Is this test flaky?

Possibly. If #151139 also fails, then I'd suggest closing the tree.

What is this? This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing c9af9c1 (parent) -> a6acf0f (this PR)

Test differences

Show 3 test diffs

3 doctest diffs were found. These are ignored, as they are noisy.

  10. arm-android: 5780.5s -> 5312.3s (-8.1%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
