windbg自行下载的sos.dll存放路径“..\SOS_x86_x86_4.7.3132.00.dll\5B5543296ee000\”里的“5B5543296ee000”是什么？

问题的引出

我在调试某个崩溃问题时，要跟踪clr的栈，于是，我先执行了指令.loadby sos clrjit，没有报错，然后我又执行!clrstack，结果却有如下输出：
0:000:x86> !clrstack
CLRDLL: Consider using ".cordll -lp <path>" command to specify .NET runtime directory.
Failed to load data access DLL, 0x80004005
Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
            2) the file mscordacwks.dll that matches your version of clr.dll is
                in the version directory or on the symbol path
            3) or, if you are debugging a dump file, verify that the file
                mscordacwks_<arch>_<arch>_<version>.dll is on your symbol path.
            4) you are debugging on supported cross platform architecture as
                the dump file. For example, an ARM dump file must be debugged
                on an X86 or an ARM machine; an AMD64 dump file must be
                debugged on an AMD64 machine.

You can also run the debugger command .cordll to control the debugger's
load of mscordacwks.dll. .cordll -ve -u -l will do a verbose reload.
If that succeeds, the SOS command should work on retry.

If you are debugging a minidump, you need to make sure that your executable
path is pointing to clr.dll as well.
也就是说执行失败了，看不了栈，根据输出建议执行.cordll -ve -u -l，有如下输出
0:000:x86> .cordll -ve -u -l

傻子都知道发生了什么问题，就是没有“mscordacwks_x86_x86_4.7.3132.00.dll”和"SOS_x86_x86_4.7.3132.00.dll"，由于我机子是联网的，也配好了windows符号服务器，应该说在上面的过程中应该已经下载下来了，现在没有，只能是到出问题的机器上考这两个文件了。

考了这两个文件，按理说我可以放在任何目录，可是我想放载windbg设置的符号目录，于是我将考过来的"mscordacwks.dll"和"SOS.dll"改名为“mscordacwks_x86_x86_4.7.3132.00.dll”和"SOS_x86_x86_4.7.3132.00.dll"，然后在windbg设置的符号目录下以这两个文件名新建两个子文件夹，把这两个文件分别考到对应的子文件夹，在次执行 .cordll -ve -u -l，跟上次输出一样，我看了下之前Windbg自行下载的其他版本的目录，发现，在还有一级目录，如下：

也就是说，我也还要需要在建立一级子目录，可是这个目录名称我该用什么呢，瞎折腾一阵，我后来注意到 .cordll -ve -u -l的输出有这么一句：

0:000:x86> .cordll -ve -u -l

也就是加载成功了。
