--- Comment #8 from David Binderman <dcb314 at hotmail dot com> ---
I see this problem also, with this reduced C code:

char **Gif_ClipImage_gfi_0;
int Gif_ClipImage_y, Gif_ClipImage_shift;
void Gif_ClipImage(void) {
  for (; Gif_ClipImage_y >= Gif_ClipImage_shift; Gif_ClipImage_y++)
    Gif_ClipImage_gfi_0[Gif_ClipImage_shift] =
        Gif_ClipImage_gfi_0[Gif_ClipImage_y];
}

Flag -O3 -march=bdver2 required.
