cname of cname of cname not working in bind 9.8.0

[PATRAULT Frederic]

Hello,

Migrated from v9.4.2 to v9.8.0 and found a strange thing, when i create a cname of a cname of a cname

ex.

gagagaga.test.com.                 IN      CNAME   gagaga.test.com.
gagaga.test.com.                 IN      CNAME   gaga.test.com.
gaga.test.com.                 IN      CNAME   ga.test.com.
ga.test.com                       IN           A             1.1.1.1

then i nslookup gagagaga on the bind server for example (true for slaves & clients too) randomly i have an error message : Non-existent host/domain
when i spam " nslookup gagagaga" sometime it works sometime it does not (ex 8 out of 10 times its ok , 2 times its not, then its 7 not ok out of 10 etc)

i had no problem with v9.4.2 and downgraded to v9.7.3 (same configuration) and i have no problem at all with v9.7.3
