   3    local-alloc screwed up consideration of high+lo_sum and created
   4    reg_equivs that it shouldn't have, resulting in lo_sum with
   5    uninitialized data, resulting in segv.  The test has to remain
   6    relatively large, since register spilling is required to twig
   7    the bug.  */
