Comment (by pdimov):

 `CA` is `allocator<char>` and there is no guarantee for `p1` to be aligned
 at anything, regardless of what the alignment of `value_type` is.

 Although I suppose that the code already assumes that `p1` is aligned at
 `alignof(value_type)` anyway. But this assumption doesn't seem quite
 correct.
