GWP‑ASan Based Heap Memory Error Detection and Debugging on Windows

This article explains how GWP‑ASan, a low‑overhead sampling memory‑sanitizer developed by Google, can be integrated on Windows to detect heap errors such as use‑after‑free, buffer‑underflow, buffer‑overflow and double‑free, describes its monitoring principles, hook implementation, crash‑report augmentation, and presents real‑world case studies and remediation strategies.
