Ok, this is my last message on this topic.
I explained in great detail what my patch is trying to fix and
why. You have the non-MAN_PN case, you aren't affected by my patch at
all. On the other hand, I don't have a MacOS and I can't reproduce the
problem you're describing in the non-MAN_PN case. Please submit your
own fix for your problem, and let me deal with my unrelated problem,
thank you.
