Repro Code
class Foo {
public getItself(): this {
return this;
}
protected then(resolve: () => void): void {
resolve();
}
}
ESLint Config
module.exports = {
parser: "@typescript-eslint/parser",
rules: {
"@typescript-eslint/no-unsafe-return": "error",
},
};
tsconfig
Expected Result
No error, nor ESLint crash.
Actual Result
ESLint will crash because of an infinite recursion of the discriminateAnyType
function in type-utils/dist/predicates.js
Additional Info
When a class has a method return this
and this
is also a Thenable, discriminateAnyType
tries to checker.getAwaitedType
on it. I assume it results in the same this
type, which is then recursively checked infinitely.
