C++ HeapWalk块枚举返回不在堆中的地址

背景：在我的工作（运行Windows XP Embedded的工业CNC机器）中，我们有一个进程，通过使用VirtualAlloc和VirtualLock系列函数将所有内存锁定到物理RAM中

我知道，在这一点上，将内存锁定到物理RAM可能不会带来以前的好处（在以前的Windows版本中，如NT），但我们正面临一个最后期限，因此，尽管我们可能能够在将来研究删除它，但目前这是一个困难的要求

因此，最近我对该进程使用的dll进行了更改，这反过来带来了更多dll，其中一些dll创建了自己的堆（除了进程加载的其他库中已经创建的堆之外）

代码（psuedocode）的基本结构为：

因此，这是伪代码，实现是用C编写的（我在每次调用Windows函数时都使用GetLastError和FormatMessage进行了正确的错误检查）

好的，所以问题是，以前，被锁定的大小是数据块大小和块开销的总和，但是使用的ptr是块中数据的ptr，所以有些情况下，VirtualAlloc和VirtualLock会重叠，越过堆进入下一堆，并因无效内存访问而失败

在我修复了这个问题之后，现在有一个块在第二次VirtualAlloc（使用MEM_COMMIT）期间失败，并出现了相同的“无效内存访问”错误

“heap\u entry”结构中给出的地址是0x00b00020。奇怪的是，根据SysInternals工具VMMap（到目前为止，它在帮助我诊断之前的问题时精确到字节）报告堆本身从0xA40000到0xA50000，但是从HeapWalk函数返回的地址是0xb00020，这是完全错误的

事实上，最后两个块超过0xA50000范围：

如您所见，它一直保持在0xA40000范围内，直到出于某种原因到达0xA60000->0xAF0000范围，然后转到0xB00020地址

我很困惑。无论是否在块枚举期间锁定堆，此问题都会持续存在。并且标志is has set表示分配了块

好吧，我会逐一锁定。也许我应该一次把它们都锁上？此物理内存锁定仅在应用程序初始化期间发生

有人知道这里会发生什么吗？我很困惑，想不出其他方法来获取更多信息
