Search Terms: Maximum call stack size exceeded

Code

class Hex<Data=any> {
    constructor(public q: number = 0, public r: number = 0, public data: Data = null) {
        
    }

    /**
     * Creates a child class that extends Hex, and initializes by default
     * with data = `defaultData`
     * 
     * @param defaultData 
     */
    static extend<Data>(defaultData: Data) {
        return class extends this<Data> {
            constructor(q: number, r: number, data?: Partial<Data>) {
                super(q, r, Object.assign({}, data, defaultData));
            }

            static defaultData = defaultData;
        }
    }
}

Expected behavior: tsc -watch works fine

Actual behavior: tsc -watch crashes, although tsc works fine

This was a duplicate, when removing the extra code I get the same error log.

@coyotte508 can you share a self contained repro with a tsconfig.json file that we can try locally?
