OK, I will try to make innd remember the message-ID.

Yes, this is now logged with my new patch and I still need to remember
the message-ID.

Yes, that was exactly the bug I saw:  as the message-ID was unknown, it was
not logged.
In such cases, we might for instance use the message-ID provided in the
argument of TAKETHIS/IHAVE; I have not checked yet whether it is easy
to do.

Yes, I understand.

That is exactly what I am going to do.
I will tell you when I commit the patch to CURRENT.

The more important thing was to fix the segfault you saw.  (Which was done.)
