Sigh! Yes, it still does. However, it goes on:

    memcpy(im, sim, sizeof(*im));

    /* reset all pointers */
    im->red = im->green = im->blue = im->alpha = 0;
    im->red_lut = im->green_lut = im->blue_lut = im->alpha_lut = 0;
    im->gray = 0;
    im->ci = 0;
    im->red16 = im->green16 = im->blue16 = im->alpha16 = 0;
    im->packed = 0;
    im->wlut = 0;
    im->llut[0] = im->llut[1] = im->llut[2] = 0;
    im->extra_io_info = 0;
    im->info = 0;

There are actually a heap more pointers that these defined in the struct, but 
I guess that it's here that we should reset the fpin and fpout pointers, no?
