exception on function that defines a pointer to a union

[GoogleCodeExporter]

What steps will reproduce the problem?

The struct xpmem_id is a length of 8.
I know there are other ways to do this, but
this function causes an exception in just loading
the script.

static void
show_id(long id)
{
        union locid {
                struct xpmem_id sid;
                long lid;
        } *lup;
        long local_id;

        local_id = id;
        lup = (union locid *)&local_id;

        printf("(pid %d uniq %d partid %d)",
                lup->sid.tgid, lup->sid.uniq,
                lup->sid.partid);
}

What is the expected output? What do you see instead?

exception, and failure to load the script

What version of the product are you using? On what operating system?

Luc, you saw this already.  This is just a
memory jogger.
