如何解决x32dbg中‘TraceOverConditional mod.user(cip)’提示以正常调试MASM程序?
解决x32dbg调试MASM程序时的界面空白与命令错误问题
问题情况
我用EasyCode IDE学习MASM和GoASM,已经给两种汇编语言配置了x32dbg和x64dbg。编写的MASM代码如下:
.Const trouble EQU 0ABADDEEDh .Data? .Data hinst HINSTANCE NULL buffer db 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' bword dw 25 bdouble dd 0DEADBEEFh .Code start: Invoke GetModuleHandle, NULL Mov hinst, Eax ;===================== ; Write your code here ;===================== mov al,[buffer] mov al,[buffer+1] mov ax,bword mov eax, bdouble mov eax, trouble mov bdouble, eax Invoke ExitProcess, 0 End start
编译链接完全正常:
============== Project1 - Debug (Press to cancel) ==============
Assembling: Project1
Linking...
Project1.exe - No error
10110 bytes
但启动x32dbg调试时界面一片空白,点击「运行到用户代码」按钮也没任何指令输出,调试日志里反复出现这条错误:

The command "TraceOverConditional mod.user(cip)" is debug-only <--- 反复出现的错误提示 The command "TraceOverConditional mod.user(cip)" is debug-only The command "TraceOverConditional mod.user(cip)" is debug-only
解决方法
1. 排查自动执行的脚本或命令
这个错误是因为某个脚本或自定义命令调用了仅调试模式可用的TraceOverConditional命令:
- 打开x32dbg,点菜单栏「脚本」→「脚本命令」,看看有没有自动运行的脚本调用了该命令,有的话直接删掉相关代码;
- 再检查「命令」→「自动命令」,如果设置了启动时自动执行
TraceOverConditional mod.user(cip),直接删除这条自动命令; - 如果装了第三方插件,先全部禁用,重启调试器再试,排查是不是插件搞的鬼。
2. 手动加载程序调试
别通过EasyCode直接启动x32dbg,手动打开x32dbg后,通过「文件」→「打开」选择编译好的Project1.exe,再点「运行到用户代码」试试。
3. 确认程序架构匹配
确保你编译的是32位程序(毕竟用的x32dbg):
- 在EasyCode里检查项目设置,确认目标架构是x86,链接器参数正确,生成的是32位PE文件。
4. 重置x32dbg配置
如果上面的方法都没用,直接重置x32dbg到默认状态:
- 关掉x32dbg;
- 找到x32dbg安装目录下的
x32\config文件夹,先备份再删掉; - 重新启动x32dbg,加载程序测试。
