# VUSE <.MEMD.1167_170>
D.827_47 = #ref#1#4.23D.819_42->lengthD.194;
D.828_49 = (unsigned intD.6) D.827_47;
if (D.828_49 <= 2)
goto <bb 7>;
else
goto <bb 8>;
<bb 7>:
# VUSE <.MEMD.1167_170>
_Jv_ThrowBadArrayIndexD.121 (2);
<bb 8>:
# .MEMD.1167_171 = VDEF <.MEMD.1167_170>
(*D.820_43)[2] = 3;
#ref#1#4.27D.833_58 = #ref#1#4.15D.791_10;
D.834_59 = &#ref#1#4.27D.833_58->dataD.195;
# VUSE <.MEMD.1167_171>
D.841_63 = #ref#1#4.27D.833_58->lengthD.194;
the store to (*D.820_43)[2] aliases length.
