You are closing the socket too early! In your previous mails the code
of your debug-server closes the socket within the interrupted thread:
 (mt:thread-interrupt
 ans
 :function
 (lambda nil
   (let ((*standard-input* socket)
         (*standard-output* socket)
         (*debug-io* socket)
         (*error-output* socket)
         (*trace-output* socket)
                        (*query-io* socket))
     (unwind-protect
          (break "debug")
       (close socket)))))


However having segfaults even in this case (read from closed socket)
is not good. Will check.
