this looks like a libc bug to me. You could try uninstalling nscd if
you have it installed but don't really need it.
Apart from that, I can't help you. I will reassign this to libc6. If
somebody needs a backtrace, the info how to get one from apache is in
/usr/share/doc/apache2.2-common/README.backtrace. It might be
interesting for the libc maintainers what directory services you use
(ldap, nis, ...) or if you have done any modifications
to /etc/nsswitch.conf.
Cheers,
Stefan
