Article: How a 20 year old bug in GTA San Andreas surfaced in Windows 11 24H2 by Adrian (Silent)

I had to pull out some long buried knowledge of C++ and stack tracing to understand Adrian’s debugging techniques, but this was fun! I love his illustrations of the stack later on in the article, explaining how Windows 11 24H2’s LeaveCriticalSection function call caused an override to the stack space used by frontWheelScale and rearWheelScale. Uninitialized variables that rely on input data that hasn’t been thoroughly validated is a scary line to walk. Be careful, and use default/fallback values!
