Bug 501766

Description of problem:

nscd periodically crashes, every couple of days.  No messages anywhere.  I've built a version of nscd that changes its working directory to /var/db/nscd instead of / so that I am able to generate a core file.  Only collected a single core file so far, of not much use:

Core was generated by `/usr/sbin/nscd'.
Program terminated with signal 11, Segmentation fault.
