Perhaps we need a new compiler warning: "hole in structure due to
non-natural alignment, please consider adding explicit padding"?
Sounds reasonable but I am afraid in 99% of cases this would be completely irrelevant and not break anything so the acceptance would be pretty low.
On a second thought, that warning might get some acceptance if it is formulated slightly differently.. making it more clear that the way the struct is arranged will waste memory in addition to creating potential portability problems?
It will not always waste memory, only if some members can be moved
into holes.
Anyway, not wasting memory is merely an optimization.
Creating portability problems is a bug,
