Strange segmentation fault in libkrb5.so.3.3 (1.6.4-beta1)

[Greg Hudson]

I suspect this is:

http://krbdev.mit.edu/rt/Ticket/Display.html?id=6681&user=guest&pass=guest

which should be fixed in the forthcoming krb5 1.8.1.

If I'm correct, the pam_krb5 code could work around the bug, but I'm not
sure if there's a configuration workaround.
