Should we move this into the Go 1.14 release? @bcmills

bcmills · 2019-11-12T18:00:52Z

Maybe? I think #35541 is pretty clearly worth investigating, since that's on real hardware, but it's not clear to me that a failure that only occurs on darwin-arm64-corellium is necessarily worth tracking down. (It would be great if we could get the actual-hardware iOS builders running stably enough to see whether it occurs on those.)

bcmills · 2021-12-09T14:59:09Z

Haven't seen any more of these on darwin-arm64-corellium since 2019.
(#50063 tracks a similar issue on a current darwin-arm64 builder.)
