Reduced testcase:

_Bool data[128];
void foo (_Bool *init)
{
 int i;
 for (i = 0; i < 128; i++)
   data[i] = *init;
}


gcc_checking_assert (types_compatible_p (TYPE_MAIN_VARIANT (TREE_TYPE (sc)),
                                           TREE_TYPE (vectype)));

fails since VECTYPE is vector(16) <unnamed-unsigned:8>
and the scalar type is _Bool
