C의 모든 것은 정의되지 않은 동작이다

Understanding that undefined behavior is a standard constraint—not merely a compiler optimization artifact—is critical for C/C++ developers, as seemingly correct code can fail unpredictably on different hardware or with future compiler versions. Subtle UBs like unaligned memory access and unsafe type casting permeate production codebases worldwide but often go undetected until deployment, exposing a systemic quality gap in legacy systems. Addressing this at scale requires combining LLM-assisted automated detection with expert human validation, a challenge too nuanced for manual review or junior-level oversight.
