tsc TypeError: Cannot read property 'flags' of undefined

[koloboid]

TypeScript Version: 2.4.1

Code

// This is minimal chunk of code
class BaseType<T> {
    bar: T
}

class NextType<C extends { someProp: any }, T = C['someProp']> extends BaseType<T> {
}

class Foo extends NextType<Foo> {
    someProp: {
        test: true
    }
}

const foo = new Foo();
foo.bar.test

Expected behavior:
Just to compile and run. May be this code violates TypeScript rules, but the actual result is unexpected, anyway
Both atom-typescript and WebStorm EAP consider this code as valid, and even correctly auto-complete "foo.bar.test"

Actual behavior:

$ tsc
/usr/lib/node_modules/typescript/lib/tsc.js:55776
                throw e;
                ^
