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. > Are you saying that tracing into update_window_line and then > update_text_area for these two, you see that the loop which starts at > line 3598 ends with i's value smaller than > desired_row->used[TEXT_AREA], and you see these 3 lines (3696 to 3698) > being executed: That does not seem to happen, no.
