| --message 'Dear @*T-miri*, | |
| It would appear that the [Miri cron job build]('"https://github.com/$GITHUB_REPOSITORY/actions/runs/$GITHUB_RUN_ID"') failed. | |
| This likely means that rustc changed the miri directory and | |
| we now need to do a [`./miri rustc-pull`](https://github.com/rust-lang/miri/blob/master/CONTRIBUTING.md#importing-changes-from-the-rustc-repo). | |
| Would you mind investigating this issue? | |
| Thanks in advance! | |
