   <bb 5>:

is the first difference and that difference is there up to *.optimized.
sizeof(bid_Kx192) is 768 bytes, so the aligned(16) attribute looks bogus, so
maybe just invalid testcase?
If one uses typedef struct __attribute__((aligned(16))) { unsigned long long
w[3]; } UINT192;
where the type then has 32 bytes in size, 16 byte alignment, rather than 24
bytes in size, then it works fine.
