Changed my mind based on the discussion in
http://lists.debian.org/debian-hppa/2006/01/msg00001.html.  The only
way that the above instruction can cause an invalid exception is

  The current instruction is a load of the destination register of
  a pending, trapping instruction (see page 10-5 of arch, delayed
  traps).

The instruction can cause the usual memory faults (i.e., check value
in sp).  In either case, the real problem is somewhere else.
