To diagnose Use-After-Free (UAF) and heap corruption bugs in complex C++ game codebases:
- Enable Pageheap in GFlags (
gflags.exe /p /enable target_game.exe /full). - Pageheap places an inaccessible guard page (
PAGE_NOACCESS) immediately following every dynamic allocation. - Attach WinDbg.
- When a dangling pointer reads freed memory or overflows a buffer by even 1 byte, the CPU triggers an immediate page fault and WinDbg breaks on the exact offending instruction!
