App Verifier just moves HeapAlloc allocations, but the C/C++ functions default to using these, so it grabs pretty much everything. For game development I wrote a custom allocator that redirects all of our allocations to the Windows heap instead of using our custom allocator, in order to support App Verifier and xperf memory profiling. It's not similar to valgrind. It's more like Electric Fence.
