Confirmed.
(gdb) p i
$1 = 144
(gdb) l
4004      for (i = first_moveable_pseudo; i < last_moveable_pseudo; i++)
4005        if (reg_renumber[i] < 0)
4006          {
4007        int idx = i - first_moveable_pseudo;
4008        rtx other_reg = VEC_index (rtx, pseudo_replaced_reg, idx);
4009        rtx def_insn = DF_REF_INSN (DF_REG_DEF_CHAIN (i));


144 does not exist in the IR as far as I can tell.
