[C++] light_array buffer boundary assertion?

[Light-City]

light_array KeyColumnArray assert

  uint8_t* mutable_data(int i) {
    ARROW_DCHECK(i >= 0 && i <= kMaxBuffers);
    return mutable_buffers_[i];
  }
  /// \brief Return one of the underlying read-only buffers
  const uint8_t* data(int i) const {
    ARROW_DCHECK(i >= 0 && i <= kMaxBuffers);
    return buffers_[i];
  }

ARROW_DCHECK(i >= 0 && i <= kMaxBuffers); may be wrong?

static constexpr int kMaxBuffers = 3;
  const uint8_t* buffers_[kMaxBuffers];
  uint8_t* mutable_buffers_[kMaxBuffers];

when data(i) i equl kMaxBuffers, will the buffers_boundary be exceeded?

So，this is a bug?

index should [0,1, 2] but not include 3
