------- Comment #2 from pinskia at gcc dot gnu dot org  2006-10-13 03:34 -------
here is a shorter testcase:
void f(void)
{
  int i, ubound1, j, ubound5;
  int (*abc)[3];
  i = 1;
  while (1)
    {
       if (j <= 3)
         while (1)
           {
              _Bool D917;
              if (i != j)
                {
                  if (__builtin_expect (ubound1 <= 0, 0))
                    __builtin_abort ();
                  (*abc)[1] = 0;
                }
               else
                 {
                    int D916;
                    D916 = j;
                    if (__builtin_expect (D916 > ubound1, 0))
                      __builtin_abort ();
                    if (__builtin_expect (ubound5 <= 0, 0))
                      __builtin_abort ();
                  }
               j = j + 1;
               if (D917)
                 break;
           }
    i = i + 1;
  }
}
