--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:

*a;
b;
f ()
{
  int c;
  while (b)
    if (-b > c)
      {
        int d, e;
        for (; e < d; e++)
          a[e] = d;
      }
    else
      {
        int d, e;
        for (; e < d; e++)
          a[e] = a;
      }
}
