为什么此程序在地址上免费使用细分故障堆堆

Question

程序试图创建多个Webrtcbin元素以从不同来源接收媒体 同一程序在Windows上正常运行，但在Mac中给出了细分故障。 在Mac上，如果For循环迭代多次迭代，那么我会得到细分错误

static void on_offer_created(GstPromise *promise, gpointer data)
{
  GstWebRTCSessionDescription *offer = NULL;
  const GstStructure *reply;
  gchar *desc;
  gchar *sdp_string;
  gchar *json_string;
  reply = gst_promise_get_reply(promise);
  GstElement *webrtc;
  webrtc = gst_bin_get_by_name(GST_BIN(gst_pipe), (gchar *)data);
  g_assert_nonnull(webrtc);
  gst_structure_get(reply, "offer", GST_TYPE_WEBRTC_SESSION_DESCRIPTION, &offer, NULL);
  gst_promise_unref(promise);

  g_signal_emit_by_name(webrtc, "set-local-description", offer, NULL);

  sdp_string = gst_sdp_message_as_text(offer->sdp);
  g_print(" offer created:\n%s\n", sdp_string);
  JsonObject *sdp_json = json_object_new();
  json_object_set_string_member(sdp_json, "type", "offer");
  json_object_set_string_member(sdp_json, "sdp", sdp_string);
  json_object_set_string_member(sdp_json, "from", ourid);
  json_object_set_string_member(sdp_json, "to", (gchar *)data);

  json_string = get_string_from_json_object(sdp_json);

  soup_websocket_connection_send_text(connection, json_string);
  g_print("sending offer to %s",(gchar *)data);

  gst_webrtc_session_description_free(offer);
}
static void
on_negotiation_needed(GstElement *webrtc, gpointer user_data)
{
  GstPromise *promise;
  g_print("negosiation  needed");
  promise = gst_promise_new_with_change_func(on_offer_created, (gchar *)user_data, NULL);
  g_signal_emit_by_name(webrtc, "create-offer", NULL, promise);
}

  for (int i = json_array_get_length(chain)-1; i >= 0; i--)
  {
    peerid = (gchar *)g_malloc0(sizeof(gchar*)*9);
    webrtc  =(GstElement*)g_malloc0(sizeof(GstElement*));
    peerid=json_array_get_string_element(chain, i);

    webrtc = gst_element_factory_make("webrtcbin", peerid);
    g_assert(webrtc != NULL);

    gst_bin_add_many(GST_BIN(gst_pipe), webrtc, NULL);
    GstCaps *caps = gst_caps_from_string(TRANS_AUDIO_CAPS);
    g_signal_emit_by_name(webrtc, "add-transceiver", GST_WEBRTC_RTP_TRANSCEIVER_DIRECTION_RECVONLY, caps, NULL);

    g_signal_connect(webrtc, "pad-added", G_CALLBACK(on_incoming_stream), &peer_delay);
    g_signal_connect(webrtc, "on-negotiation-needed", G_CALLBACK(on_negotiation_needed),g_strdup (peerid));
    g_signal_connect(webrtc, "on-ice-candidate", G_CALLBACK(send_ice_candidate_message), g_strdup (peerid));
    g_assert_true(gst_element_sync_state_with_parent(webrtc));

  }

我正在使用libsoup进行插座连接。失败了，我更改了图书馆，现在正常工作
