OK, so ...

If you're getting a parse error on that line, the problem must be that
`id -u` is returning *nothing* (it might very well be dumping core as
well).  Since `id -u` only prints an integer, it must be the case that
it's unable even to obtain that integer, which means that one of

      euid = geteuid ();
      ruid = getuid ();
      egid = getegid ();
      rgid = getgid ();

is failing catastrophically.

As zsh also calls these library routines, that's probably the cause of
the crash.
