I recompiled an SBCL 1.1.9, which is close to your and just
before it upgraded to ASDF 3.0.2, and couldn't reproduce your issue;
can you give me steps to reproduce, if possible minimal?

Also, is your sbcl install the fruit of a cp -r without timestamp
preservation? Are there clock skew issues between your host and e.g.
an NFS server?

In your TRAVERSE output, what we're looking for is the first
compilation of a lisp file. It's also possible that some static-file
with a high timestamp cause the next system over to think it must be
