[clisp-list] bug report: too many arguments to +

[Bruno C. <ca...@it...>]

hello everybody;

  clisp version 2.33.2 appears to show a problem when you try to add
more than 4095 numbers (e.g., integers) as in

(progn
  
  (setq l nil)
  
  (dotimes (i 4096)
	   (push i l))
  
  (apply #'+ l)
  
  )


The message error displayed on breaking into the debugger is:

*** - APPLY: too many arguments given to +


Now, 4096 is a quite suspect number isn't it? (some #define BUF_SIZE
of sorts?). Oddily enough, also, function #'- works at 4096, but fails
at 4097 ....

Much older version 2.27 does not show the problem: #'+ happily digests
hundreds of thousands of arguments, and when it finally fails (say at
500000), it does so because of stack overflow.

*** - Lisp stack overflow. RESET


In fact, this is more in tune with a recursive implementation of #'+.


- Has anyone heard of this before?
- Anyone able to confirm these behaviours?

thanks in advance;

bruno
