"Debug adapter process has terminated unexpectedly" when debugging on window used mingw gdb

OS: WIN7 64BIT
VSCODE: 1.19.1
MINGW: 0.6.2 GDB: 7.6.1

i can compile and debug use g++ and gdb on windows console.

but when i using vscode and c++ plugin for debug, it was always said "Debug adapter process has terminated unexpectedly" !
i still try with restart vscode and windows, but nothing change

it's my launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "C++ Launch (GDB)",
"type": "cppdbg",
"request": "launch",
"targetArchitecture": "x86", // i had try x86, x64, x86_64, still the same error
"program": "d:\workspace\test\test.exe",
"windows": {
"MIMode": "gdb",
"miDebuggerPath": "gdb.exe" // gdb path is in my windows environment variable
},
"args": [],
"environment": [],
"stopAtEntry": false,
"cwd": "d:\workspace\test\",
"externalConsole": false,
"preLaunchTask": "g++",
"logging": { "engineLogging": true }
}
]
}

also nothing log output.
any suggest?
thank you for help.

Inizia con il launch.json fornito su Windows 7, verificando le impostazioni windows MIMode, miDebuggerPath, targetArchitecture e preLaunchTask. Riproduci il problema esaminando la registrazione configurata del motore e la risoluzione di gdb.exe; il lavoro è completato quando la sessione di debug C++ viene avviata correttamente in VS Code invece di terminare inaspettatamente.
