Typescript 2.4.0+ Stack overflow

example.ts

export interface Foo<T> {
  (bar: Bar<T>): void;
}

export interface Bar<T> {
  (foo: Foo<T>): Foo<T>;
}

function createBar<T>(): Bar<T> {
  return (f) => f;
}

function foo<T>(
  bar: Bar<T>,
): void {}

// Operator '===' cannot be applied to types 'Foo<{}>' and 'string'.
createBar()(foo) === '1';

// Operator '===' cannot be applied to types '<T>(bar?: Bar<T>) => void' and 'number'
foo === 1;

// Stack overflow
createBar()(foo) === foo;
