A New Debugging Mindset

Debugging shifts from guesswork to evidence: record-and-replay debuggers like rr and Undo capture full execution so you can follow corrupted data backwards instead of replaying runs or adding logs that often lack clues. Traditional debuggers only show the current instruction; reversible debugging lets you go to the failure point, step backward over the exact execution, and inspect the root cause. Practical result: far fewer blind reruns and much faster isolation of memory corruption, concurrency, or logic bugs.
