nil exit status usually means a crash.

Probably, but would like to get a workaround to avoid having to continue merging other PRs with red CI (only reason this formula might run on self-hosted is due to dep tests).

As I recall, this has been the behavior for a while but we've just ignored it as part of dep tests and just merged the failed runs.

Would need someone interested in figuring out exact reason. I don't think we've seen any user reports of issue. It could just be issue running in GCP.

Specifically, would like these merged before I start the final run for #193114 where some dep tests fail only due to running on self-hosted.

Plan to kick it off in an hour or so.
