------- Comment #4 from irar at il dot ibm dot com  2010-08-10 09:06 -------
I am testing the same patch as in comment #1.

Testcase that shows the problem:

int
foo(short x)
{
  short i, y;
  int sum;

  for (i = 0; i < x; i++)
    y = x * i;

  for (i = x; i > 0; i--)
    sum += y;

  return sum;
}
