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？
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
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?
