Summary: continuations contain stuff they shouldn't
Initial Comment:
Chris Double reports the following bug in 1.9.2-rc:
I'm having a problem serializing continuations where it
can't serialize some of the objects in the
continuation, but that object shouldn't be in the
continuation (I think). The problem does not occur with
1.8.8. Here is a test case that reproduces the problem
(if not the same problem, a similar one):
;; I used a ServletHttpResponse that I saved from a request
(define a ...some object that can't be serialized...)
(define test-param (make-parameter #f))
(define (doit p)
(test-param p)
(set! p #f)
(call-with-serial-output-file "test.ser" (lambda
(port) (call/cc
(lambda (k) (serialize k port))))))
;; This succeeds as it should
(doit a)
;; This gives an error that it can't serialize the
ServletHttpResponse, again as it should
(call-with-serial-output-file "test.ser" (lambda (port)
(serialize a port)))
;; Now this fails with the same error and always fails
from now on
(doit a)
If I repeat the same steps in 1.8.8 things work fine.
The final (doit a)
succeeds.
