I do
gdb> run -Q
and continue a few times until Emacs starts up. If I then select the
Emacs window with the mouse, it breaks twice, so I have to reselect the
gdb window to get it to continue, and then when I select the Emacs
window... Anyway, I can get around that by alt-tabbing back into Emacs.

That does not seem to happen, no.
I have i = stop = 13 = desired_row->used[TEXT_AREA].
