通过 bp kernelbase!RegOpenKeyExW 设置断点在 WinDbg 中不起作用
Setting Breakpoint via bp kernelbase!RegOpenKeyExW Doesn't Work in WinDbg
使用 WinDbg Preview 或来自 Windows 10 SDK 的 WinDbg，在 Windows 10 1909（内部版本 18363.815）上启动 32 位进程时，在 kernelbase 上设置断点！RegOpenKeyExW 按名称不起作用.
示例：
- 在 WinDbg
下启动 C:\windows\syswow64\notepad.exe
- .symfix C:\symbols
- .重新加载
- bp ntdll!NtOpenKeyEx

我可以使用通配符通过 bm 设置断点，但在过去我从来没有这样做过：
0:000> bm kernelbase!RegOpenKeyExW*
1: 74bc64b0 @!"KERNELBASE!RegOpenKeyExW"
2: 74bb4a20 @!"KERNELBASE!RegOpenKeyExW"
想知道是否有任何特定更改导致此问题，或者符号等问题？
好吧，一个是 CLRTYPE 私有符号，我不知道它是怎么进来的，但 iirc 有几个像这样的符号
使用 .symopt+4000 仅加载 public 个符号
那么你的断点将被正确设置

使用 WinDbg Preview 或来自 Windows 10 SDK 的 WinDbg，在 Windows 10 1909（内部版本 18363.815）上启动 32 位进程时，在 kernelbase 上设置断点！RegOpenKeyExW 按名称不起作用.
示例：
- 在 WinDbg 下启动 C:\windows\syswow64\notepad.exe
- .symfix C:\symbols
- .重新加载

重新加载符号没有区别：

我可以使用通配符通过 bm 设置断点，但在过去我从来没有这样做过：
0:000> bm kernelbase!RegOpenKeyExW*
1: 74bc64b0 @!"KERNELBASE!RegOpenKeyExW"
2: 74bb4a20 @!"KERNELBASE!RegOpenKeyExW"
想知道是否有任何特定更改导致此问题，或者符号等问题？
好吧，一个是 CLRTYPE 私有符号，我不知道它是怎么进来的，但 iirc 有几个像这样的符号
使用 .symopt+4000 仅加载 public 个符号 那么你的断点将被正确设置
