Fare, here are the results for quicklisp 2013-01-28 patched with asdf 2.28 and new version of asdf-system-connections: http://common-lisp.net/project/cl-test-grid/asdf/asdf-diff-6.html
As you see there are failures. One of the most often errors is "Unhandled SERIOUS-CONDITION of type COMPILE-FAILED-ERROR is signaled: Lisp compilation failed", but there are some other errors.
Best regards, - Anton
