Hi! The buildbot aarch64 RHEL8 LTO 3.x has failed when building commit 47d7eba.

What do you need to do:

1. Don't panic.
2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/338/builds/4895) and take a look at the build logs.
4. Check if the failure is related to this commit (47d7eba) or if it is a false positive.
5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.
