Data races and the limits of ThreadSanitizer in C and Go

The article highlights that while ThreadSanitizer is an important safeguard for finding concurrency bugs in C and Go, it has meaningful blind spots that can let data races slip into production unnoticed. For CIOs and technology leaders, the business risk is clear: undetected concurrency defects can create intermittent outages, corruption, and difficult-to-diagnose reliability issues that undermine engineering velocity and customer trust. IT organizations should treat race detection as one layer in a broader software quality strategy, combining sanitizer-based testing with architecture reviews, load/stress testing, and concurrency-safe design practices.
