GFlags and PageHeap
https://msdn.microsoft.com/zh-cn/library/ff549561(v=vs.85).aspx
现在GFlags包含了PageHeap(pageheap.exe)的功能,可以在Windows中监视堆的分配。(PageHeap enables Windows features that reserve memory at the boundary of each allocation to detect attempts to access memory beyond the allocation.)PageHeap能够根据Windows特点,在每块分配的内存边界存储来探测试图访问越界内存。
