[Bug tree-optimization/32225] New: ICE in alias.c with INDIRECT_REF to a INTEGER_TYPE

[pinskia at gcc dot gnu dot org]

quantize_fs_dither (unsigned width, short *errorptr, int dir)
{
  short bpreverr;
  unsigned col;
  for (col = width; col > 0; col--) 
    errorptr += dir;
  errorptr[0] = (short) bpreverr;
}

SCCP goes funny for this (have not looked why yet).
