with one dimension much larger

   It is due to integer overflow. The return type of the first 
value`shape_.Size()` is index_t, which is defined as `unsigned`. The value 
700000x128x128 exceeds the UINT_MAX range. The return type of the second value 
`mshadow::Shape shape.Size()` is size_t, which equals to 64-bit unsigned long. 
Therefore, it reports CHECK_EQUAL failure.
