--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!
Sincerely,
The Miri Cronjobs Bot'
