How an Off-by-One Error Caused a Silent Data Corruption Bug
from The Software Engineering Podcast with Fexingo: Code, Architecture, and Engineering Best Practices Hosted by Fexingo
Episode 127 of The Software Engineering Podcast dives into a notorious class of bugs: off-by-one errors. Lucas and Luna explore a real-world case where a single misplaced increment in a C++ memory allocator silently corrupted data for months before discovery. They trace how the bug passed code review, evaded unit tests, and ultimately required a formal verification tool to catch. Along the way, they discuss why off-by-one bugs are so insidious, how modern languages like Rust try to eliminate them, and practical techniques like fencepost testing and invariant assertions that every engineer should know. If you've ever spent hours staring at a loop boundary, this one's for you. #OffByOneError #SoftwareEngineering #MemoryCorruption #CPlusPlus #BugStory #CodeReview #FormalVerification #RustLang #FencepostError #Debugging #MemorySafety #Technology #SoftwareEngineeringPodcast #Fexingo #FexingoBusiness #BusinessPodcast #Programming #BestPractices Keep every episode free: buymeacoffee.com/fexingo
