TypeScript版本： 3.9.0-dev.20200223, 3.8.2
搜索词： 查找所有引用crash tsserver reexport
代码

Reproduction repo
file1.ts

export class Foo {}
export class Bar {}

file2.ts

import * as f1 from './file1';

export class Container {
    readonly classes = f1;
}

declare const c: Container;
c.classes.Foo;

// Uncommenting this line make 'Find all references' work again
// export { f1 };

file3.ts

import { Container } from './file2';

declare const c: Container;
// 'Go to definition' works from here but 'Find all references' doesn't show this line
c.classes.Foo;

预期行为：

所有三个对 Foo 的引用都会显示，分别在 file1.ts 、 file2.ts 和 file3.ts 中。

实际行为：

在 file3.ts 中的引用没有显示。

解决方法？:

取消注解 // export { f1 }; 在 file2.ts 中，使得所有引用都能被找到，即使没有其他文件导入 f1。
编辑(2020-02-23):我在同一个仓库中测试了这部分内容，使用 TS 3.8.2 时不再导致 tsserver 崩溃。但是在同一个仓库中，当使用新文件 file4.ts 时，发现在 Foo 上查找所有引用会导致 tsserver 崩溃。将 file4 更改为：

import { S } from './file3';

可以避免崩溃。在 tsserver.log 中显示：

{"seq":11,"type":"request","command":"references","arguments":{"file":"/tmp/find-references-ts-bug/file3.ts","line":5,"offset":12}}
Err 109   [19:9:26.28] Exception on executing command {"seq":11,"type":"request","command":"references","arguments":{"file":"/tmp/find-references-ts-bug/file3.ts","line":5,"offset":12}}:
