我在其中一个应用中遇到了崩溃的minidump文件。它是一个32位的本机应用程序，它运行在64位Windows上。
如果我将minidump文件加载到WinDbg中，WinDbg将不会加载系统DLL的符号。我已正确配置了符号路径：
_NT_SYMBOL_PATH=SRV*C:\WebSymbols*http://msdl.microsoft.com/download/symbols
...因为WinDbg正确加载了在32位Windows上创建的小型转储的符号。它只是不会在SysWOW64目录中加载DLL的符号。
我在32位Windows 2003上尝试过32位WinDbg（来自调试工具6.9），在64位Windows 2008上尝试过64位WinDbg（也来自调试工具6.9）。两者都无法加载符号。这是来自32位WinDbg：

有什么想法吗？这些符号在Microsoft的符号服务器上是不可用的吗？
答案 0 :(得分：4)
您是在32位还是64位系统上调试，还是使用32位或64位版本的WinDBG？您通常必须在从转储中获取的相同体系结构包上进行调试：

“32位版本的Windows调试工具是最佳选择，除非您在64位处理器上调试应用程序。在这种情况下，您应该使用64位软件包。”
另外，看看这篇文章，他正在调试在64位平台上运行的32位应用程序：

考虑这里提到的解决方法，其中syswo64 \ ntdll.dll被复制到Syswow64 \ ntdll32.dll
