In versions of Kawa prior to 1.7, the following macro would always
return "worked" when given one argument:

(define-syntax t1
  (syntax-rules (literal)
    ((t1 literal)
     "worked")
    ((t1 a)
     (t1 literal))))

Now there's a stack overflow. I think the prior behavior was correct.


I checked in a fix, as well as your testcase.
