Hello Release Team, I don't think I can do anything about this bug. Upstream aren't able to reproduce it. I don't think it makes sense to block sbcl's migration on this. I think that either we should ignore the cl-ironclad test failure on ppc64el or remove sbcl on that architecture, if you think that would be warranted. Please let me know if you would be okay with overriding the test failure. Thanks. -- Sean Whitton
