File: backtrace
Do you have the core dump from this crash? When I get a TGT for nalin/admin here, and wait for it to expire, I don't see a crash. Based on the partial klist output you gave above, the strcmp() call should be comparing two non-empty, correctly terminated strings, so it really shouldn't be triggering a segfault there. Additionally, just to rule out any variation, are you also using glibc-2.13-1.x86_64? Thanks for your interest in this issue. I installed some more debuginfo files, obtained a core file, and traced it. I'll attach the compressed core file and the trace. I've also confirmed that I'm using glibc-devel-2.13-1.x86_64.

backtrace
Ah, I see what's going on now. The klist output was truncated at the interesting part: the crash is happening while examining credentials for "host/vcs.hetzner.co.za" with no realm name, which suggests that referrals were involved in getting the ticket for that server, and that's something that the KDC I usually use doesn't support yet. With a one-off test KDC, it was pretty easy to reproduce. krb5-1.8.4-2.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/krb5-1.8.4-2.fc14 Package krb5-1.8.4-2.fc14: * should fix your issue, * was pushed to the Fedora 14 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing krb5-1.8.4-2.fc14' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/krb5-1.8.4-2.fc14 then log in and leave karma (feedback). krb5-1.8.4-2.fc14 has been pushed to the Fedora 14 stable repository.
