Visual Studio crashes with Generics

[falsandtru]

TypeScript Version: 2.0.6

1. clone https://github.com/falsandtru/pjax-api
2. open the project via pjax-api.csproj
3. open src/lib/dom.ts
4. add the angle brackets for generics as follows
5. move the cursor inside the angle brackets
6. crash immediately

// add
  }, Object.assign<>({}, option, { capture: true }));
                    ^ cursor
// move
  }, Object.assign<>({}, option, { capture: true }));
                   ^ cursor

simplified repro

declare function f(a: any, ...b: any[]): any;
f<|>(1, 2)

if signature help is requested at position | script side returns result where isVariadic is set to true but parameter list is empty which seems to be illegal combination for Roslyn SignatureHelpItem
