#382 fixed write-string / write-simple-string error Gary Byers R. Matthew Emerson
Description
? (funcall #'(lambda () (write-string "foobar" t :end 2)))
> Error: value NIL is not of the expected type UNSIGNED-BYTE.
> While executing: (:INTERNAL BAD-SEQUENCE-INTERVAL CHECK-SEQUENCE-BOUNDS), in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

 (6A5978) : 0 (FUNCALL #'#<(:INTERNAL BAD-SEQUENCE-INTERVAL CHECK-SEQUENCE-BOUNDS)> "foobar" NIL 2) 181
 (6A59A8) : 1 (FUNCALL #'#<#<STANDARD-KERNEL-METHOD STREAM-WRITE-STRING (BASIC-CHARACTER-OUTPUT-STREAM T)>> #<BASIC-CHARACTER-OUTPUT-STREAM ISO-8859-1 (TTY/1) #x300040EF978D> "foobar" NIL T) 669
 (6A5A40) : 2 (WRITE-SIMPLE-STRING "foobar" T NIL 2) 1637

We see that WRITE-SIMPLE-STRING is getting NIL as the START parameter.

I'm not sure if the problem here is with the compiler macro on WRITE-STRING, or with WRITE-SIMPLE-STRING.

We could change the compiler macro to provide a default value of 0 for the start keyword argument, or else we could change the WRITE-SIMPLE-STRING deal with a possibly NIL value for START in the case where the stream isn't a basic-stream, e.g., by writing (or start 0) in the call to STREAM-WRITE-STRING.

(I'd just go ahead and change the compiler macro, but i assume that WRITE-SIMPLE-STRING is a performance hack, and I don't want to mess that up.)

#383 fixed (setf (char (make-string 1) -1) #\1) "crashes" the CCL process Gary Byers Johan Lindberg
Description

(setf (char (make-string 1) -1) #\1) "crashes" the CCL process.

It's the -1 that's causing the trouble. And I know that it's not valid code since the ANSI standard clearly states that the index must not be negative. But I expected to be thrown out into the debugger, not to have the CCL process just die.

I run Mac OS X 10.5.5 and have installed Clozure CL 1.2-rc1-intel.dmg from May 9 2008.
