------- Comment #1 from rguenth at gcc dot gnu dot org  2010-07-29 10:01 -------
Confirmed, mine.

We generate wrong constraints for

bar (int * * x)
{
  int * D.2737;

<bb 2>:
  D.2737_3 = MEM[(struct Foo *)x_1(D) + -8B].p;
  *D.2737_3 = 0;
  return;

}

Generating constraints for bar (bar)

bar.arg0 = &NONLOCAL
D.2737_3 = *bar.arg0
bar.use = bar.arg0
bar.clobber = D.2737_3

I have a patch.
