Note that RFC1912 ( https://tools.ietf.org/html/rfc1912 )
says:

"Don't use CNAMEs in combination with RRs which point to other names
like MX, CNAME, PTR and NS."

"having chained records such as CNAMEs pointing to CNAMEs may
make administration issues easier, but is known to tickle bugs in
some resolvers"
