The mozilla/rr debugger doesn't work on Ryzen CPUs - https://github.com/mozilla/rr/issues/2034

(rr stands for Record and Replay Framework, it's a gdb extension which allows for reverse execution)

Interesting that GDB had its own "time travel" support for longer that afaik works on AMD. Will have to see what rr brings to the table.

GDB's recording is extremely limited. It doesn't even work on multi threaded programs.

It's also about 1000x slowdown during recording, where rr is < 2x.
