#472 Hang on read-char-no-hang after clisp 2.41

[Angel Popov]

on clisp 2.41 (send-hi) works as expected, but on clisp 2.42, 2.43 and 2.44 it hangs on read-char-no-hang

(defun send-hi (socket)
(with-open-stream (s socket)
(format s "GET /authentication/login HTTP/1.1
COOKIE:NIL
PACKET-ID:3
USER:clisp
CLIENT-CHANNEL:clisp
COOKIE-TEMPLATE:clisp
AUTHENTICATE:PLAIN
ENCRIPTION:NONE

")

(format t " 1 reply from server ~A~%" (read-line s nil nil))
(format t " 2 reply from server ~A~%" (read-line s nil nil))
(format t " 3 reply from server ~A~%" (read-line s nil nil))
(format t " 4 reply from server ~A~%" (read-line s nil nil))
(format t " 5 reply from server ~A~%" (read-line s nil nil))
(format t " 6 reply from server ~A~%" (read-line s nil nil))
(format t " 7 reply from server ~A~%" (read-line s nil nil))
(format t " 8 reply from server ~A~%" (read-line s nil nil))
(format t " 9 reply from server ~A~%" (read-line s nil nil))
(format t "10 reply from server ~A~%" (read-line s nil nil))
(print (read-char-no-hang s nil nil))
(print (read-char-no-hang s nil nil))
(print (read-char-no-hang s nil nil))))

(send-hi (socket:socket-connect 9001 "im.webmessenger.com" :external-format :dos))

it works on

thank you for your bug report.
the bug has been fixed in the CVS tree.
you can either wait for the next release (recommended)
or check out the current CVS tree (see http://clisp.cons.org\)
and build CLISP from the sources (be advised that between
releases the CVS tree is very unstable and may not even build
on your platform).
