This is fixed in Symbolics CLIM 2.1, if you can manage to obtain a copy.

   Hi,

   While trying to evaluate the form

   (clim:filling-output (*nanesse-logging-stream* 
				   :fill-width '(100 :character))
       (format *nanesse-logging-stream* "format-string" args))

    in clim2, I obtain the following bug (Note that this code worked perfectly 
   well in clim 1.1) :

   Error: TO-END is out of bounds.
   While in the function COPY-ARRAY-PORTION <- REPLACE <-  #<CLOS:STANDARD-METHOD 
   CLIM-LISP:STREAM-WRITE-STRING  (CLIM-INTERNALS::FILLING-STREAM T) 60242746>

   COPY-ARRAY-PORTION
      Arg 0 (SI:FROM-ARRAY): #<ARRAY STRING-CHAR 128 simple 30340174>
      Arg 1 (SI:FROM-START): 99
      Arg 2 (SI:FROM-END): 101
      Arg 3 (SI:TO-ARRAY): #<ARRAY CHARACTER 100 fill-pointer 101 224104773>
      Arg 4 (SI:TO-START): 99
      Arg 5 (SI:TO-END): 101
   s-A:          Return to Breakpoint ZMACS in Editor Typeout Window 1
   s-B:           Editor Top Level
   s-C:           Restart process Zmacs Windows
   -> Abort Abort
   Return to Breakpoint ZMACS in Editor Typeout Window 1
   Trap: The subscript given to the SYS:FAST-AREF-1 instruction, 100, on #<ARRAY 
   CHARACTER 100 fill-pointer 101 224104773> was beyond the length, 100.
   While in the function CLI::POSITION-POSITIONAL <- #<CLOS:STANDARD-METHOD CLIM-
   LISP:STREAM-WRITE-STRING (:AROUND) (CLIM-INTERNALS::OUTPUT-PROTOCOL-MIXIN T) 
   60254504> 
   <- #<CLOS:STANDARD-METHOD CLIM-INTERNALS::FILLING-STREAM-WRITE-BUFFER (CLIM-
   INTERNALS::FILLING-STREAM) 60242652>

   CLI::POSITION-POSITIONAL
      Arg 0 (CLI::ITEM): #<CHARACTER-STYLE NIL.NIL.NIL 13000000>
      Arg 1 (SEQUENCE): #<ARRAY CHARACTER 100 fill-pointer 101 224104773>
      Arg 2 (LT:TEST): #<Compiled function EQL 507424175>
      Arg 3 (CLI::TEST-NOT): #<Compiled function EQL 507424175>
      Arg 4 (CLI::KEY): #<Compiled function SI:CHAR-STYLE 507603477>
      Arg 5 (CLI::FROM-END): NIL
      Arg 6 (CLI::START): 0
      Arg 7 (CLI::END): 101
   s-A:           Ask for a different subscript
   s-B:           Return a value from the FAST-AREF-1 instruction
   s-C:           Retry the FAST-AREF-1 instruction
   s-D:           Return to Breakpoint ZMACS in Editor Typeout Window 1
   s-E:           Editor Top Level
   s-F:           Restart process Zmacs Windows
   ->Abort Abort
   Return to Breakpoint ZMACS in Editor Typeout Window 1
   The program cannot safely be aborted at this time.
   The function CLIM-INTERNALS::INVOKE-FILLING-OUTPUT is executing a cleanup form.
   Aborting before the cleanup is complete could leave the program in
   an inconsistent state and cause it to operate incorrectly later.
   Do you want to Skip or Abort? Abort
   Back to Breakpoint ZMACS.

   I found very strange that the argument 
       (SI:TO-ARRAY): #<ARRAY CHARACTER 100 fill-pointer 101 224104773>
   of the function COPY-ARRAY-PORTION is a 100 elements array and the fill-pointer 
   has the value 101.

   Has somebody already seen such a bug?

   Thanks for any help.
