WARNING: program timed out. FAIL: 20_util/hash/chi2_quality.cc execution test This appears to have come from revision r205810. I can't find the discussion or approval leading to that commit. It seems likely to have been a mistake, perhaps a commit intended for a local repository. Why else increase the workload, without discussion with other target maintainers known to risk being affected by this change? The somewhat obvious fix is to just revert revision r205810.
