gud mode + scilab mode problems with lambda expression

[Eviatar Tron]

when I try to run gdb or dbx from emacs, I get
the following error:
gud-common-init: Wrong number of arguments: (lambda (s bag) (cond ((equal
(length s) 0) (quote (""))) ((string-match bag s) (if (= (match-beginning 0)
0) (cons "" (split-string (substring s (match-end 0)) bag)) (cons (substring
s 0 (match-beginning 0)) (split-string (substring s (match-end 0)) bag)))) (t
(cons s nil)))), 1

the same happens when I run scilab:

scilab-find-recent-variable-list: Wrong number of arguments: (lambda (s bag) 
(cond ((equal (length s) 0) (quote (""))) ((string-match bag s) (if (= 
(match-beginning 0) 0) (cons "" (split-string (substring s (match-end 0)) 
bag)) (cons (substring s 0 (match-beginning 0)) (split-string (substring s 
(match-end 0)) bag)))) (t (cons s nil)))), 1

thanks
