Sorry, I got too specific in my comments and did not provide enough detail. The structure in question is unioned with a communications buffer. The code assumes the structure will fit in the buffer, but there are no checks. It just so happens that the structure extends beyond the communications buffer (from the alignment issue I think - hence my question.

In any event, the result is that the structure's data is truncated with values lost at the end. Luckily, the last 200 bytes or so are spare, so no harm or foul but lousy coding all the same.
