@types/node + typescript@1.9.0-dev.20160521-1.0 results in duplicate identifier 'stack' error

[IgorMinar]

TypeScript Version:

1.9.0-dev.20160521-1.0

Code

Install node d.ts file:

npm install --save-dev @types/node@4.0.21-alpha

index.ts:

console.log('hello');

tsconfig.json:

{
    "compilerOptions": {
        "noImplicitAny": true,
        "strictNullChecks": true,
        "moduleResolution": "node",
        "pretty": true,
        "allowSyntheticDefaultImports": true,
        "skipDefaultLibCheck": true,
        // output options
        "outDir": "dist/",
        "rootDir": "./src",
        "module": "commonjs",
        "target": "es6",
        "declaration": true,
        "sourceMap": true,
        "inlineSources": true
    },
    "files": [
        "src/index.ts",
        "node_modules/@types/node/index.d.ts"
    ]
}

Expected behavior:

the build should work

Actual behavior:

tsc errors with:

11:24:25 PM - File change detected. Starting incremental compilation...

       ~~~~~

Looks like a duplicate of #8675

[DanielRosenwasser]

Yup, same issue, and we agreed that we'd be fixing it at the last design meeting (#8724). I'll close this in the mean time.
