Bug 222599

I use the cdbmake package that is written by Dan Bernstein and it is used to
compile a list of email addresses from a text file and make a .CDB database.
In order to parse the text file in to a proper format, a shell script called
cdbmake-12 is used to set it up properly. File listed below

#!/bin/sh
# WARNING: This file was auto-generated. Do not edit!
awk '
  /^[^#]/ {
    print "+" length($1) "," length($2) ":" $1 "->" $2
  }
  END {
    print ""
}
'
I snipped off the pipe to the actual cdbmake program at the end of the script
because the problem happens before it gets called.

After making a text file with the contents.
testing1
testing2
testing3


Then going to the command line and executing.
./cdbmake-12 validrcpt.cdb validrcpt.cdb.tmp < fakemail.txt

It works fine. But if I change the fakemail.txt to:

testing1.us
testing2.us
testing3.us


Then run the above command, I get:

[root@intranet ~]# ./cdbmake-12 validrcptto.cdb fakemail.txt.tmp < fakemail.txt
> debugdat.txt

As you can see from the command line that I ran, I redirected the output to
debugdat.txt and that contains.

+29,0:testing1.us->
+29,0:testing2.us->


Of course this is not my list of real email addresses but with my real list I
get same results.

I am running Fedora Core 5 with these RPM packages installed in case you need to
know.

gawk-3.1.5-6.3
glibc-2.4-11
glibc-common-2.4-11
glibc-devel-2.4-11
glibc-headers-2.4-11
kernel-2.6.15-1.2054_FC5
I do have kernel-2.6.18-1.2257.fc5 but it acts up.

Any help would be appreciated. I don't know if this is a gawk, glibc, or kernel
problem.  By the way, I do have a development machine that runs Fedora Core 4
and I have no problems with it.

Thanks,
Scott Chandler
