Unfortunately I do not have saved the original problem. I remember that I found
it in randomized testing and that it was rare. I also remember that it was a
real wrong-code error that I had to spend a day or so to track down.

I will try to make an effort in finding a "real" error again by running some
more randomized testing during the weekend.
