In object Ada, this is not necessary provided the type specifications are explicitly size constrained and the object fits in between its address and the next objects address. In other words if there is a gap between the end of one object and the beginning of the next object, the data is read correctly (if the size of the type is explicitly constrained).

When compiled with GNAT, did GNAT spit out any Warnings at all? I would suspect misaligned address value during run time should have warned during compilation.
