Looking into it.

Reduced testcase is:

--cut here--
int aa_renderpalette (int p)
{
  int y = 42;
  int i;

  for (i = 0; i < 256; i++)
    {
      if (y > 255)
        y = 255;
      if (y < 0)
        y = 0;

      if (p)
        y = (y < p ? 0 : (y > p) * 255 / (255 - 2 * p));
    }
    return y;
}
--cut here--
