It doesn't work for pointers (pr42709):

+int
+main1 (int *a, int *b, int *c, int *d, int dummy)
+{
+  int i;
+
+  for (i = 0; i < N/2; i+=4)
+    {
+      res[i] = a + 16;
+      res[i+1] = b + 16;
+      res[i+2] = c + 16;
+      res[i+3] = d + 16;
+      if (dummy == 32)
+        abort ();
+    }
+}
