Question

我正在尝试分析wow64进程转储。问题是内存泄漏，所以我需要检查堆。我指的是这篇文章来分析转储：

找不到wow64！_TEB32，所以无法继续。整个身体有没有帮助呢？

Answer 1

首先，确保您的symbols are set up correctly，通常是

.symfix c:\symbols
.reload

通常，对于32位应用程序，如果您不想自己调试WOW64层，则应该进行32位转储。

但是，在您的情况下（关于!heap命令），您可以重复32位版本的WinDbg中的步骤，该版本也可以在64位Windows上运行，并且可以打开64位转储。

哇！！找不到_TEB32
