I've build fresh ECL yesterday on Windows XP with MS Visual Studio.

I am testing Hunchentoot (the port to ECL is suggested in

Most of 20 examples in hunchentoot-test site work, but in one
case error happens.

I've tracked it down to the following test case (original error
location is flexi-streams):

(defun stream-type (stream)
  (declare (optimize speed (safety 0) (space 0)
                     (debug 1) (compilation-speed 0)))
  (cond ((and (input-stream-p stream)
              (output-stream-p stream))
        ((input-stream-p stream)
        ((output-stream-p stream)

(defun test ()
  (with-open-file (in "C:/some-file"
                      :element-type '(unsigned-byte 8))
    (stream-type in)))


(compile 'stream-type)
=> NIL

Removing (declare (optimize ...)) from stream-type definition
makes both compiled and interpreted versions work equally.
