Attribute align does not work that way for arrays.  ints have size 32 
bits, and thus a random array element has only 32-bit alignment.  Even 
if we align the base address of A to 128 bits, A[1] is that address plus 
32-bits, and thus can only have 32-bit alignment.  If you want each 
array element to have 128-bit alignment, then the array elements must 
each be 128-bits in size.
