h264_frame_start() clears h->er.cur_pic, and decode_nal_units() only sets it again for pictures that are not field coded, right before running error concealment. A second field goes through neither, so h->er.cur_pic keeps pointing at whatever frame coded picture the context decoded earlier. With frame threading the two fields of a pair are decoded by different contexts, so whether this triggers depends on what the context that picks up the second field decoded before, which is why the number of bogus warnings varies between runs.
