------- Comment #2 from rguenth at gcc dot gnu dot org  2010-04-18 20:14 -------
Loop invariant motion breaks this.

 <bb 6>:
-  g_313.0_6 = pretmp.4_9;
-  *g_313.0_6 = 0B;

 <bb 8>:
   # m_21 = PHI <0(11), m_3(D)(2)>
+  g_313.8_12 = *g_313.0_6;
+  g_313.0_6 = pretmp.4_9;
   goto <bb 5>;

we insert stmts not preserving ordering.
