SCI: Marked the sanity check inside processWorkList() as a workaround
The sanity check added in rev #35086fe17c fixes the crashes with that
code when an invalid reference is about to be processed, but these
references shouldn't be in the stack at all in the first place, so the
root cause seems to be somewhere else.
