Yeap it should be the test case issue on the difference between BE and LE:
For a buff `\001\002\003\004\005\006\a\b\t\n\v\f\r\016\017\020\021\022`,
after loading to a vector right justified, the result is different between =
BE
and LE.
e.g. for a vector (from 128bit view: 0x0000000000000000102030405060708),=20
from v16_int8 view on BE, it is v16_int8 =3D {0x0, 0x0, 0x0, 0x0, 0x0, 0x0,=
 0x0,
0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8}; but from the v16_int8 view on=
 LE,
it is v16_int8 =3D {0x8, 0x7, 0x6, 0x5, 0x4, 0x3, 0x2, 0x1, 0x0, 0x0, 0x0, =
0x0,
0x0, 0x0, 0x0, 0x0}.

So, we would just need to update the expected result for BE for this test c=
ase.=
