Windbg 为什么呢！heap-s heap没有按预期的方式工作？,windbg,Windbg,我的WinDBG版本是10.0.10240.9 AMD64，在随意调试一些本机内存转储时，我意识到我的！heap命令的行为和前面描述的不同，我不知道为什么有很多资料提到！堆-s：当我执行时！堆-s 我得到了这个被截断的列表： 0:000> !heap -s ***************************************************************************************************************

我的WinDBG版本是10.0.10240.9 AMD64，在随意调试一些本机内存转储时，我意识到我的！heap命令的行为和前面描述的不同，我不知道为什么

有很多资料提到

！堆-s

：

当我执行

时！堆-s

我得到了这个被截断的列表：

0:000> !heap -s

好的，

看起来很大，但与上面的文档和

相反！heap-s-？

我无法获取此堆的信息，这些命令中的每个命令都会产生与上面所示完全相同的输出（好像我不会在-s之后指定任何内容）：

我得到一个虚拟块的负载和一个所有堆的转储，而不是一个指定的堆
有人有相同的问题吗？

这可能是一次散步，
无法回答win 10版本不起作用的原因：-（
试试Insider Preview SDK Build 14965中最新的Windbg：为什么问题很难回答…它也被分解成10.0.10075.9、10.0.10586.567、10.0.14321.1024。它在6.3.9600.17298中工作。@magicandre1981官方WDK发行版14321.1024可以工作，但只使用
-h heap
语法。@ThomasWeller测试了10.0.14321.1024，使用
！heap-s-h
，运行正常。我的测试结果来自Windows 7 SP1 x64。您在Windows 10上吗？
