Smaller testcase for -O -g:

int a, b;

int
bar (void)
{
  int i, j = 1;
  for (i = 0; i != 10; i++)
    {
    lab:
      if (i)
    {
      int *k = &j;
    }
      else if (j)
    goto lab;
    }
  return 1;
}

inline int
foo (int x)
{
  unsigned int c = x;
  int d = x;
  if (bar ())
    for (; c; c++)
      while (x >= 0)
    if (foo (d) >= 0)
      {
        d = bar ();
        a = b ? b : 1;
      }
  return 0;
}
