Whatever you do to reproduce this, please keep all your steps
identical, so that values reported in different messages are
consistent.  If you need to change the steps for some reason, please
make sure that the values you reported in previous mails are still the
same, or if not, show the new values.  TIA.

??? This is entirely unexpected, since it3.current shows that the
iterator is at position 445.  I'm probably missing something important
here...

What do these commands produce:

 (gdb) p top
 (gdb) p start
 (gdb) p end
 (gdb) p top_y
 (gdb) p (g-20)->object

Can you describe or produce a snapshot of the screen before that C-n
keypress?

Thanks.
