There are stepping commands in the sldb buffer:
  s -- sldb-step
  o -- sldb-out
  x -- sldb-next

For SBCL:
  s calls sb-ext:step-into
  o calls sb-ext:step-out
  x calls sb-ext:step-next

And sb-impl::enable-stepping is called automatically by those commands.
So it looks like the commands do something reasonable.

If I add (declare (optimize debug)) to your fib function then the
commands seem work.
