sometimes variables are not available in the debugger, even with (debug 3)

[Attila Lendvai]

take this example:

(defun test ()
  (declare (optimize (debug 3)))
  (let (foo
        bar)
    (print foo)
    (print bar)
    (setf foo 1)
    (setf bar 1)
    (break "~S" bar)))

FOO will not be visible in the debugger, only BAR.

when removing the setf, or changing it to (setf bar nil), then BAR also disappears.

in general removing anything else from the example, makes BAR disappear.
