TypeScript版本： 3.8.0-dev.20191122
源代码：

interface PromiseAction extends Promise<Action> {}
type Action = {type: string} | PromiseAction;
const createFooAction = async (): Promise<Action> => {type: "foo"};

tsconfig.json

{
  "compilerOptions": {
    "target": "es2017",
    "allowSyntheticDefaultImports": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "noImplicitAny": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "strictNullChecks": true,
  },
  "include": ["src/**/*"]
}

预期行为：

成功进行类型检查或抛出一些错误

实际行为：

tsc崩溃，报错信息为RangeError: Maximum call stack size exceeded

你用你的定义制造了一个无限类型的循环：

interface PromiseAction extends Promise<Action> {}
type Action = {type: string} | PromiseAction;

PromiseAction 需要 Action ,而 Action 需要 PromiseAction 。

搜索词：promise,递归，崩溃，async?
你创建了一个无限类型的循环
是的，但编译器不应该因此崩溃。根据这种递归的形式，递归类型通常是可以接受的。这个看起来足够无害。
我想问题出在编译器如何评估async函数上。

type Action = { type: string } | Promise<Action>; // okay TS3.7
function acceptAction(action: Action) { } 
acceptAction({ type: "" }); // okay
acceptAction(new Promise(res => res({ type: "" }))); // okay
acceptAction(Promise.resolve(Promise.resolve(Promise.resolve({ type: "" })))); // okay
function f(): Promise<Action> { return Promise.resolve({ type: "" }) }; // okay
async function g(): Promise<Action> { return Promise.resolve({ type: "" }) }; // kablooey
