Hi,

I am trying to rewrite the work with sockets in a swank via IOLib and found that call peek-char produces an error "No uncommitted character to unread" (see %stream-unread-char in a gray-stream-methods.lisp) . I did not understand deep, but noticed that after the following simple modifications:

diff --git a/src/streams/gray/gray-stream-methods.lisp b/src/streams/gray/gray-stream-methods.lisp index d0cdbce..43f4694 100644 --- a/src/streams/gray/gray-stream-methods.lisp +++ b/src/streams/gray/gray-stream-methods.lisp @@ -320,7 +320,6 @@ (unread-index ibuf-unread-index-of) (ef external-format-of)) stream - (setf unread-index (iobuf-start ib)) (let* ((str nil) (ret nil) (encoding (babel:external-format-encoding ef)) (max-octets-per-char

system begins to work normally
