Mentioned on chat, but the CI failure here is because a test that runs the upstream test suite (I think) is failing. This seems to be the failure:

../../../boost/test/utils/lazy_ostream.hpp:82:29:   required from ‘std::ostream& boost::unit_test::lazy_ostream_impl<PrevType, T, StorageT>::operator()(std::ostream&) const [with PrevType = boost::unit_test::lazy_ostream; T = boost::test_tools::tt_detail::print_helper_t<boost::multiprecision::number<boost::multiprecision::backends::cpp_int_backend<> > >; StorageT = const boost::test_tools::tt_detail::print_helper_t<boost::multiprecision::number<boost::multiprecision::backends::cpp_int_backend<> > >&; std::ostream = std::basic_ostream<char>]’

it's regression. Passed with boost-1.78.0-11.fc38. Reported 2231976, 2231977.

@spot given the above, why did you waive the failure?

The boost code hasn't actually changed since the last update

... and thats why I waived it. My change literally symlinked a directory that made an obscure build tool that boost makes work. There is almost a 0% chance what I did is related to the failure, and it was blocking my package which depends on that build tool.
