prove/src/asdf.lisp uses (make-instance 'asdf:load-source-op) but this is not correct,
and this is disallowed in asdf 3.2 (so it can rely on hash-consing for equality testing and enable future developments). Can you instead use (asdf:make-operation 'asdf:load-source-op) or even, in this context, just 'asdf:load-source-op ?
