[PATCH] ieframe: Fix position vs. length check in the go_forward() helper.
by Dmitry Timoshkov 24 Jan '22

24 Jan '22

This->travellog.position is 0 based while This->travellog.length is a total counter. So, with current comparison if(This->travellog.position >= This->travellog.length) go_forward() would jump to an invalid index if position == 1 and length == 2. This patch fixes a crash while navigating html help file that I have here.
