[halcy0n at gentoo dot org]

The following testcase triggers an ICE on 4.1.1 20060410:

static int NumLevels = 16, ImageWidth = 640, ImageHeight = 350;
int
main (int argc, char **argv)
{
  int i, j, FlipDir;
  unsigned char Color;
  unsigned char *Line;
  for (Color = NumLevels, i = 0; i < ImageHeight; i++)
    {
      for (j = 0; j < ImageWidth; j++)
        Line[j] = (FlipDir ? 1 : Color);
    }
}

gcc -O1 -maltivec -ftree-vectorize ../giflib.x.i
../giflib.x.i: In function 'main':
../giflib.x.i:4: internal compiler error: in emit_move_insn, at expr.c:3162
