ONE:

(std::__1::vector<int, std::__1::allocator<int> > [3]) $0 = {
  [0] = size=0 {}
  [1] = size=0 {}
  [2] = size=0 {}
}

TWO:
I'm initializing all of them, so why are they NULL? :S

(std::__1::vector<int, std::__1::allocator<int> > *[3]) $1 = {
  [0] = 0x0000000000000000
  [1] = 0x0000000000000000
  [2] = 0x0000000000000000
}

THREE:
It stays "size = 0", when it should be "size = 3". Right?

(std::__1::vector<std::__1::vector<int, std::__1::allocator<int> >, std::__1::allocator<std::__1::vector<int, std::__1::allocator<int> > > >) $2 = size=0 {}

FOUR
This is NULL as well! :s

(std::__1::vector<int, std::__1::allocator<int> > **) $3 = 0x0000000000000000
