Description
In ref_pic_list_struct(), strp_entry_sign_flag parsing is conditioned to AbsDeltaPocSt, and AbsDeltaPocSt derivation depends on sps_weighted_pred_flag and sps_weighted_bipred_flag.
But sps_weighted_pred_flag and sps_weighted_bipred_flag are parsed after ref_pic_list_struct() in the SPS !
Thus the parsing depends on not already parsed syntax element in the SPS.

This was fixed in the software in MR1007:

Note: See TracTickets for help on using tickets.
Good catch! It seems that sps_weighted_pred_flag and sps_weighted_bipred_flag in the SPS should be moved to be just before log2_max_pic_order_cnt_lsb_minus4.
