I did a git bisect, this bug is caused by sbcl commit
c63557933adae1f6a46250056a8ba53bfb7ead02, I think this part
is relevant:

"Also move TUNE-IMAGE-FOR-DUMP into DEINIT so that any
compiling caused by user code as a consequence of
calling *save-hooks* is done first."

See
https://github.com/sbcl/sbcl/commit/c63557933adae1f6a46250056a8ba53bfb7ead02
they move "(tune-image-for-dump)" inside "(deinit)",
which is after "#+sb-thread (finalizer-thread-stop)".

If we move "(tune-image-for-dump)" before
"#+sb-thread (finalizer-thread-stop)", then there is no problem.

This is very strange after all, and I will report to sbcl
developers soon.
