I have no reasons to believe the test case will not reproduce the
problem. The reply that is expected from me is whether the proposed
patch is correct or not, and for that it is not enough to confirm that
the test case is reproducible. I don't have the answer yet.
FWIW, this code was not touched since Emacs 21.1 was released. So
evidently the effects of this issue are quite subtle in practice.

You can help if you explain in more detail what is wrong with the
current code. That is what I need to assess the correctness of the
patch. I hoped that Yamamoto-san would do that. Failing that, I'll
need to figure it out myself, which will take more time, and thus will
have to wait a couple of days until I have that time to sit down and
look into this. I do intend to do that, make no mistake.

It would be better to describe the problem you are seeing, if not a
recipe to reproduce it.
Alternatively, you could apply the patch and see if those problems
disappear.
