Dear CMU CL hackers, ASDF 3.2.0 moved a few symbols from asdf/action to the later asdf/plan: required-component, traverse-actions, traverse-sub-action. But when I compile asdf.lisp while asdf 3.1.7 is loaded, the fasl ends up containing the symbols in action/action, and unfbound symbols are created in asdf/plan and exported. CMUCL is the only implementation that does that, and I believe that is a recent change, because test-utilities.script didn't fail before I upgraded CMUCL from some 2016 snapshot to the latest 2017-01. If that doesn't ring a bell, I can investigate further. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Be humble, for you are made of earth.
