On a CentOS 5 (Final) machine with sendmail-8.13.8-2.el5 installed, I
grabbed the sendmail-8.13.8 source tarball and copied out cidrexpand.
When I run it, though, it just sits and does not return to a command
prompt. It creates a 0 length output file but does nothing else. I
ran a strace, and the last few lines are:

Any idea what's wrong?

Could you post "command line" you use to run cidrexpand?
Based on the above cidrexpand waits for input via standard input (STDIN).
The cidrexpand perl script reads STDIN unless you give names of input
files via command line.

you may use "per map" command like below to compile access table:
#v+
cd /etc/mail
cidrexpand < access | makemap hash access
#v-

What I use is.....

$ cat /usr/sbin/fix-cidr
#!/bin/sh
/usr/sbin/cidrexpand < /etc/mail/access | makemap -r hash /etc/mail/access

I run that after I add any new cidr's.
