- sfink 11y agoI've used it, and I've been using rr. gdb's reverse debugging was useful to me a few times, in extremely limited situations. I often do my initial runs under rr, just in case I might want to debug, because it's useful most of the time and it's not enough overhead to worry about. gdb's reverse debugging works after you narrow the range of interest down to a very small region, because otherwise its buffer will repeatedly overflow and it'll take ages.
