<pre>
    I am using the following code: https://godbolt.org/z/K4ffnE6jv
The generated `%struct.outerStruct = type <{ i8, i8, %struct.innerStruct, i8, [13 x i8] }>` will not allow the innerStruct's 'intArray' to be aligned to 16 bytes.

If the code is changed to the following: https://godbolt.org/z/zY7PWejMK (**_Alignas(16)**` struct innerStruct tt;`)
The generated IR will be correctly aligned:
`%struct.outerStruct = type { i8, i8, [14 x i8], %struct.innerStruct, i8, [15 x i8] }`

I am trying to understand if this is a bug, undefined interaction between the `packed` and `aligned` attributes or perhaps invalid/undefined code.
