The string builder has nothing to do with this; V8 defines a maximum string length of about 268 million characters (in class String in objects.h):
// Maximal string length. static const int kMaxLength = (1 << 28) - 16; This is not a bug and unrelated to numbers being 64-bit doubles; it's just an implementation-defined limit. I don't think there's anything you can do to get longer strings.
