Apart from gdb and lldb, rr is another powerful debugger that is quite helpful in debugging multi-threaded code which is harder to debug due to its non-determinism. Often, when debugging multi-threaded code, a certain section of code triggers a bug but fails to reproduce in subsequent executions of the program.
The rr debugger can perform a reproducible debugging session for non-deterministic, multi-threaded code. It does this by recording the debugging session, which you can replay and track incrementally to close in on the issue. It does this by first saving the trace of the program to disk with all the required information to reproduce the program execution.
One of the limitations of rr is that it is only supported on Linux and on Intel CPUs as of now. To set up...
