Assertion failed: class_id < rt->class_count

[Omnomios]

If you call qjs::Context::registerClass after you have torn down and recreated a QuickJS instance it will assert with an error saying that the Class ID is too high.

This is happening because js_traits<std::shared_ptr<T>>::QJSClassId is a static member and does not get reset when the qjs::Context is destroyed.

I patched it to use a map in the context to keep track of the assigned IDs and if the map has been reset then reset the js_traits<std::shared_ptr<T>>::QJSClassId to zero.

Not sure of the best way to go about this but it was a workaround for me.

    template <class T>
    void registerClass(const char * name, JSValue proto = JS_NULL)
    {
        auto hashId = typeid(T).hash_code();
        if(this->classIds.count(hashId) == 0 && js_traits<std::shared_ptr<T>>::QJSClassId != 0)
        {
            js_traits<std::shared_ptr<T>>::QJSClassId = 0;
        }
        js_traits<std::shared_ptr<T>>::register_class(ctx, name, proto);
        this->classIds[hashId] = js_traits<std::shared_ptr<T>>::QJSClassId;
    }
