For the record, here is what seems to be the crucial difference in the generated code.

Old (gives incorrect results):

        /* INLINED CODE (index) */
        ti4_1 = (EIF_INTEGER_32)  0;
        ti4_1 = *(EIF_INTEGER_32 *)(RTCV(tr1)+ _LNGOFF_2_1_0_0_);
        /* END INLINED CODE */

New (gives correct results):

        /* INLINED CODE (index) */
        ti4_1 = (EIF_INTEGER_32)  0;
        ti4_1 = *(EIF_INTEGER_32 *)(RTCV(tr1)+ _LNGOFF_1_2_0_0_);
        /* END INLINED CODE */

It seems that there is a difference in the offset calculation, such that rev 82636
now gives correct results.
