STINNER Victor <vstinner at python.org> added the comment:

We have 4 buildbot workers running RHEL7 and using LTO+PGO optimizations: aarch64, amd64, ppc64le, s390x.

I saw random failures on amd64 and s390x. amd64 failed builds:

* 910: test_reindent_file_with_bad_encoding() failed
* 911: test_reindent_file_with_bad_encoding() failed
* 914: test_reindent_file_with_bad_encoding() failed
