[Resolved]SDK V1.4.0 连接路由器后再运行mDNS会输出很多3fff0280 already freed

如题

3fff0280 already freed 某块内存已经释放了,然后再次被引用此内存才会出现的该Log信息吗?

重现步骤:
在SDK1.4.0上,8266连接上路由器并运行mDNS服务,然后打开手机上的mDNS客户端,则会输出4条以上“3fff0280 already freed”信息

重现机率:100%

补充:如果手机端的mDNS APP一直扫描局域网中的mDNS设备时,ESP8266会不断的输出3fff0280 already freed....

您好,

麻烦基于 esp_iot_sdk_v1.4.0 更新附件 lib,看您的问题是否解决?

感谢您对 ESP8266 的关注!

I have the same problem with the "already freed" errors using V1.4.1_pre7 from viewtopic.php?f=7&t=1257&start=10#p4505
Did the fix in the liblwip.a from this thread get lost in the _pre7 version?
I am also seeing problems where mDNS does not reply to certain queries, is the liblwip.a version in the v1.4.1_pre7 SDK the latest one or is there a better one to use?
