That's causing

/home/wireshark/builders/trunk/ubuntu1204x64/build/epan/dissectors/packet-bssgp.c: In function ‘de_bssgp_son_transfer_app_id’:
/home/wireshark/builders/trunk/ubuntu1204x64/build/epan/dissectors/packet-bssgp.c:3173:12: error: variable ‘next_tvb’ set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors

in the Ubuntu CMake build (I guess the automaker build isn't turning on that particular error).

The code in question is

    tvbuff_t *next_tvb;

    /* SON Transfer Application Identity: This field is encoded as the SON Transfer Application Identity IE
     * as defined in 3GPP TS 36.413
     */
    if(len > 0){
        next_tvb = tvb_new_subset(tvb, offset, len, len);
        dissect_s1ap_SONtransferApplicationIdentity_PDU(tvb, gpinfo, tree, NULL);
    }

Should it be passing next_tvb to dissect_s1ap_SONtransferApplicationIdentity_PDU()?
