    ****************************************************************
    * PROBLEM DESCRIPTION: In some rare combination of statements, *
    *                      the optimizer would move some of the    *
    *                      use of a pointer before the test to see *
    *                      if it was (sys)null. This would lead to *

    *                      null (when its use should have been     *
    *                      bypassed)                               *
