c does come directly after s. The padding between b and c is part of s. If you don't want that padding, you can use `align(1)` to define S without padding. But then 75% of the ints in an S[] will be misaligned.
I understand that. I don't want the alignment of `S` to change. I want the padding after `s` in `T` to be avoided and have `c` start at byte-offset 7. I don't see why this padding is needed in the case where only a single (1-element array of) `S` is stored as a field inside another aggregate.
Ali's code prints: === Memory layout of 'T' (.sizeof: 12, .alignof: 4) === 0: S s 8: char c 9: ... 3-byte PADDING
