That's not the point.
struct kevent declaration should be the following:
struct kevent {
uintptr_t ident; /* identifier for this event */
short filter; /* filter for event */
u_short flags; /* action flags for kqueue */
u_int fflags; /* filter flag value */
intptr_t data; /* filter data value */
void *udata; /* opaque user data identifier */
};
If this doesn't match, you'll unpack garbage when extracting members,
and since it's an unaligned access, you can even get a SIGBUS (looks
like sparc64 doesn't allow unaligned access).

Yes, we could do that on OpenBSD, but that's definitely an OpenBSD bug.
