VS Code通过gdb调试时无法找到helloworld.cpp的问题求助

• 按照微软官方VS Code C++ HelloWorld示例操作，使用Cygwin g++可正常编译运行程序，但通过GDB调试时断点无法触发
• 在launch.json中设置"stopAtEntry": true后，程序能停住，但点击main()栈帧时提示找不到helloworld.cpp文件；报错显示的路径包含高位ASCII字符，格式为C:>cygwin\bin\C☐>Users>lehrian>Documents>CProjects>HelloWorld>helloworld.cpp
• 尝试通过sourceFileMap将C:\cygwin\bin映射到\cygdrive，仅能修正路径中C☐>Users>...左侧的部分，核心问题似乎是VS Code试图使用Windows完整路径，而GDB无法正确解析其中的c:\部分
• 相同代码在Linux环境下可正常调试，现寻求解决方案，同时想确认是否有其他用户能复现该问题

调试日志补充 #

查看调试日志发现路径拼接异常：

--> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (1655) ->1023^done,stack=[frame={=\"0\",addr=\"0x000000010040108d\",func=\"main\",file=\"C:\\Users\\lehrian\\Documents\\CProjects\\HelloWorld\\helloworld.cpp\",fullname=\"/cygdrive/c/Users/lehrian/Documents/CProjects/HelloWorld/C:\\Users\\lehrian\\Documents\\CProjects\\HelloWorld\\helloworld.cpp\",line=\"5\",arch=\"i386:x86-64\"}]\r\n"},"seq":709} 1: (1655) ->1023^done,stack=[frame={level="0",addr="0x000000010040108d",func="main",file="C:\Users\lehrian\Documents\CProjects\HelloWorld\helloworld.cpp",fullname="/cygdrive/c/Users/lehrian/Documents/CProjects/HelloWorld/C:\Users\lehrian\Documents\CProjects\HelloWorld\helloworld.cpp",line="5",arch="i386:x86-64"}] --> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (1655) ->(gdb)\r\n"},"seq":711} 1: (1655) ->(gdb) 

可见fullname字段同时包含Cygwin路径和Windows路径，正确格式应为仅使用Cygwin路径（如/cygdrive/c/Users/lehrian/.../helloworld.cpp），请问是否有VS Code偏好设置或调试配置选项可以指定路径格式？
