           Version: 10.0
            Status: UNCONFIRMED

  Target Milestone: ---

The following is causing ICE:

$ cat lim.ii
struct a {
  int b;
} * c;
struct d {
  d *e;
};
struct f {
  bool done;
  d *g;
};
int h;
int i(f *j) {
  if (j->g) {
    j->g = j->g->e;
    return h;
  }
  j->done = true;
  return 0;
}
void k(bool j) { c->b = j; }
void l() {
  f a;
  for (; !(&a)->done; i(&a))
    k(true);
}

$ ./xgcc -B. /tmp/tree-into-ssa.ii -c -O2 -fsanitize=address
