A thanks to Ray who has helped.
Here's the workaround:
(defun put-char (my-stream my-char)
"Put a character on the given stream."
(if (eq my-stream t)
(write-char my-char *standard-output*)
(write-char my-char my-stream)))
(defun put-string (my-stream my-string)
"Put a string on the given stream."
(if (eq my-stream t)
(write-string my-string *standard-output*)
(write-string my-string my-stream)))

Three related bugs:
(defun bug0 (my-stream)
(write-char #\1 my-stream)
(format my-stream "~D" 2)
(write-char #\3 my-stream))
Let's see. CLHS says for write-char, T means *terminal-io*. And T
for
format means *standard-output*. Hence, write-char and format send
their
output to different places. On cmucl, *standard-output* and
*terminal-io* are different streams. Looking at the stream objects,
they go to different Unix file descriptors, and the file descriptors
are
different.
For all the tests you provide, if you specify *standard-output*, you
get
the results you want. I guess gcl and clisp have *terminal-io* and
*standard-output* being essentially the same stream.
