test failure: BUG/WALK.2

Hello.

I am running iterate tests (between other often-used CL libraries) on different Lisps.
The results of continuous testing may be found here:
http://common-lisp.net/project/cl-test-grid/pivot_ql-lib_lisp.html.

Currently Iterate has the same failure on all the lisps:

   Test ITERATE.TEST::BUG/WALK.2 failed
   Form: (ITERATE:ITER
           (RETURN
            (IF (ODDP 1)
                (PROGN)
                'ITERATE.TEST::EVEN)))
   Expected value: NIL
   Actual value: ITERATE.TEST::EVEN.

Best regards,
- Anton
