VsCode debugging with c++17 fails? - c++

Question

I'm getting an issue where I can build and run a project with c++17 flags enabled, but I can't actually debug it. The debugger launches in vsCode, but all the c++ 17 features are red squiggled, and those lines never execute properly. I'm guessing it's a problem with my launch.json, but I can't figure out what it is that I'm missing...
I'm running windows 10, and here's the relevant configuration in vsCode:
tasks.json:
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++.exe build active file",
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
"args": [
"-std=c++17",
"-g",
"${fileDirname}\\*.cpp",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Generated task by Debugger"
}
],
"version": "2.0.0"
}
launch.json:

Welp - not much of an answer, but the issue isn't happening when I just use cl.exe as the compiler instead of gcc. I've since just stopped using gcc for this project after trying to get it to work for about an hour.
