---------------------------+--------------------
 In the nominal case checked by spsysinit01, obj_err in shm_unlink is
 unmodified when _POSIX_Shm_Get_by_name returns non-NULL. In the case of
 shm_unlink, this means an uninitialized value is passed into the switch
 and it appears this test was passing by virtue of the stack having the
 right value on it in most cases.
