The patch is good, I'll apply it. But speaking of w alignment, isn't the
alignment code in AEC_init() wrong? Currently it's:

a->w = (REAL *) (((uintptr_t) a->w_arr) + (((uintptr_t) a->w_arr) % 16));

Shouldn't it be

a->w = (REAL *) (((uintptr_t) a->w_arr) - (((uintptr_t) a->w_arr) % 16) + 16 / sizeof(REAL));

?
