rr - 5.4.0-2 main

rr allows application executions to be recorded and then replayed
with gdb as many times as desired.
.
This allows intermittent, or complex to reproduce, bugs to be
captured and then debugged at leisure. Replays are deterministic,
always identical from one run to another.
.
rr is incompatible with ptrace hardening, and currently only supports
Intel CPUs with Nehalem or later microarchitectures, and some Zen
CPUs. The amd64 package supports debugging amd64 and i386 binaries.
