The following code triggers an ice on s390 with -m64:

void wmemset (int *s, int c, int n)
{
  register int *wp = s;
  while (n >= 4)
    {
      wp[0] = c;
      wp[1] = c;
      wp[2] = c;
      wp[3] = c;
      wp += 4;
      n -= 4;
    }
}

$ gcc-4.4 -m64 -O3 -c testcase.i
testcase.i: In function ?wmemset?:
testcase.i:1: internal compiler error: Segmentation fault
