Description of problem:
On November 17 I upgraded various packages to the latest updates,
among them glibc (upgraded to glibc-2.3.2-27.9.7).  On November 19 I
rebooted the system.  Since then named (which was *not* upgraded) logs
messages in syslog: XXX.zone:23: near 'CNAME': bad dotted quad.
I have not changed this configuration recently (last change was
several months and several reboots ago), and I have not changed named
since I initially installed RedHat 9 (still running bind-9.2.1-16),
which leads me to think the problem is an incompatibility with glibc.
The line named all of a sudden complained about was:

XXX IN A CNAME <n>-<m>.surfsnel.dsl.internl.net.

where <n> and <m> are numbers in the range 1-254.

Of course, there is nothing I can do about the name on the right.  It
is given to me by my ISP.

Version-Release number of selected component (if applicable):
bind-9.2.1-16 glibc-2.3.2-27.9.7

How reproducible:
Always

Steps to Reproduce:
1.Set up a primary domain, and a CNAME entry that looks like the one
above.
2.Upgrade to latest versions of RedHat 9 updates
3.Restart named
    

Actual Results:  named complained about "bad dotted quad" and served
an empty domain, making my system unreachable from the outside world.

Expected Results:  named should accept the host name on the right hand
side as valid.
