There's a far bigger problem there, which is if we're afraid that current_len_left might exceed 4GB then what is it exactly that guarantees it'll fit in an 11-digit field?
Well, we will only write 11 digits in there, that's when we read it. But print_val() on the server side should probably have an overflow check there, which it doesn't. It's going to write some strange values int here if it overflows..
