This is missed because this:
maxIdx.1_15 = (unsigned int) maxIdx_59;
D.1923_20 = maxIdx.1_15 + 1;
D.1924_21 = D.1923_20 * 4;
D.1925_22 = numbers_9(D) + D.1924_21;
and this:
maxIdx_24 = maxIdx_59 + 1;
pretmp.36_86 = (unsigned int) maxIdx_24;
pretmp.36_88 = pretmp.36_86 * 4;
pretmp.38_90 = numbers_9(D) + pretmp.36_88;
do not match. The first has the arithmetic done as unsigned, the second as
signed. This could be due to array indexing lowered to POINTER_PLUS_EXPR.
