Of course RR is too expensive to be deployed in production builds. So if you are getting core dumps from "production" you won't have this information. So while RR helps it doesn't completely mitigate the tradeoff.

You may be interested in Intel PT snapshots in Linux core dumps, that gdb knows how to interpret and will give you a detailed branch trace. Less cool than rr but still very interesting!
