bugs for cname can not be working properly with bind 9.11.4

[边明凯]

Hello ,

I have run the dns server by myself which installed centos7 and bind
version is BIND 9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.9 (Extended Support
Version) ,the domain name is kaixinduole.com

I just create a cname record for tesing ,which is www cname to www.baidu.com.
please see the below :

[root at bind-master-centos7 named]# cat kaixinduole.com.zone$TTL 1D@		IN
	SOA  ns1.kaixinduole.com. shawn.kaixinduole.com. (
								202204276								1H 								15M 								1W 								1D )		IN
	NS	ns1.kaixinduole.com.		IN 	NS	ns2.kaixinduole.com.		IN	MX 10
	mx1		IN	MX 20 	mx2		IN	A	22.3.3.95ns1		IN	A	52.130.145.30ns2		IN	A	139.217.99.188mx1		IN	A	2.1.1.7mx2		IN	A	2.1.1.7mx3		IN	A	2.1.1.7subversion	IN

~all"@		IN	TXT     "YOU CAN CONTACT ME BY PHONE 15810410643"

actually this cname record just does work properly ,the other rest of
record are woring normally .

my testing below:
