lib_dec/ivas_spar_decoder.c:1031:22: runtime error: index 60 out of bounds for type 'int16_t [60]'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior lib_dec/ivas_spar_decoder.c:1031:22 in 

The problematic line is ivas_spar_decoder.c:1013:

        while ( b == bin2band->p_cldfb_map_to_spar_band[bin] )
        {
            for ( ts = 0; ts < MAX_PARAM_SPATIAL_SUBFRAMES; ts++ )
            {
                subframe_band_nrg[b] += cldfb_in_ts_re[ts][bin] * cldfb_in_ts_re[ts][bin] + cldfb_in_ts_im[ts][bin] * cldfb_in_ts_im[ts][bin];
            }
            bin++;
        }

This could theoretically change the calculation if the out-of-bounds dereference by chance fulfills the condition. Potential fix could be to change check to

        while ( bin < CLDFB_NO_CHANNELS_MAX && b == bin2band->p_cldfb_map_to_spar_band[bin] )

or to change from while loop to do-while.
