I would agree with the assessment although, I don't know that it is
documented anywhere that this is what happens. As the previous "bug"
with the trace_events was solved by me adding .align(4) everywhere, I
would think that .align(sizeof(long)) would work here too.

It may be a good ideal to force this alignment, and not add wasted
space. If anything, if this (hypothetical) bug appears, it will most
likely show up as a crash on boot up. I'm not too concerned about it.
