What I try to do is debug the code in the interpreter and set

 > (generate-proper-tail-calls #f)

Then you'll find, e.g.,

 > (define (f n)
   (if (= n 0)
       (/ 1 n)
       (f (- n 1))))
 > (f 5)
*** ERROR IN f, (console)@11.7 -- Divide by zero
(/ 1 0)

0  f 
(console)@11:7                                              (/ 1 n)
1  f 
(console)@12:7                                              (f (- n 1))
2  f
