>Description:
I ran pwd_mkdb on the wrong file and instead of a nice error I got
sig11 and coredump. The core can be found here:
http://j.xpert.com/pwd_mkdb/pwd_mkdb.core
The input file can be found here:
http://j.xpert.com/pwd_mkdb/asd

Other bizarness:
After the core is created pwd_mkdb leaves two empty temp files:
/etc/pwd.db.tmp
/etc/spwd.db.tmp

The next time you run pwd_mkdb it errors:
pwd_mkdb: /etc/pwd.db.tmp: File exists
but it removes this file. If you run it again you'll get:
pwd_mkdb: /etc/spwd.db.tmp: File exists
which you have to remove manually if you pwd_mkdb
to start working again.
Needless to say, all the operations described here
are run as root.
>How-To-Repeat:
pwd_mkdb asd
<corefile created>
pwd_mkdb asd
<see error message>
pwd_mkdb asd
<see different error message>
