------- Comment #10 from cnstar9988 at gmail dot com  2008-08-21 12:53 -------
I am sorry for wrong test for 4.3.0.

=================================================
I rebuild my gcc 4.3.0 on 2.6.9-42.7AXsmp with gmp 4.2.3 + mpfr 2.3.1.

And make a test again. It works fail.
But the following code well on gcc 4.3.2-RC1. 
=================================================
 void xxx()
 {
  unsigned i;
  unsigned*p=2;  /* 2 is ok, but failed with 0 */
  for(i=0;i<4;++i)
  {
   *p++=0;
  }
  for(i=0;i<4;++i)
  {
   *p++=0;
  }
 }
