Thanks. I see this too. Here's a shorter program illustrating the difference.
#lang racket
(require profile)
(define (f x)
(if (zero? x)
(continuation-mark-set->context
(current-continuation-marks))
(values (f (- x 1)))))
(unless (zero? (random 1))
(set! f void))
(f 10)
Running this with a 64bit racket under windows returns the empty list,
but with a 32bit racket under windows returns a list of a bunch of
stuff:
C:\Users\robby\git\plt>Racket.exe C:\Users\robby\tmp.rkt
(list (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33 133))
(cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 3
3 133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33 133))
(cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0
33 133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33 133))
(cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4
0 33 133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33
133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt>
4 0 33 133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33
133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rk
t> 4 0 33 133)) (cons 'f (srcloc #<path:C:\Users\robby\tmp.rkt> 4 0 33
133)) (cons '|[running body]| (srcloc #<path:C:\U
sers\robby\tmp.rkt> #f #f #f #f)))
