Slogging through the code, it appears to me that the code added in block 45 to
define err2.395_571:

  D.6815_562 = Commutative_Associative_Reduction.822[0];
  err2.395_571 = D.6815_562;

...should have instead been added in block 43 to define err2.395_561.  The
removal of the close_phi would then have been correct.  I'll step through the
code to see where the wrong phi is getting selected for this.
