seg faults with 2.12 slapd and GSSAPI bind

[Ben Poliakoff <benp@reed.edu>]

I've been working on an openldap installation on a Red Hat 7.3 machine.

slapd's been giving me seg faults when I try to bind with GSSAPI.  

I'm using cyrus-sasl-2.1.12 with MIT krb5-1.2.4.

Looking at the list archives I have to start wondering if some of this
is related to the krb5 libs not being thread safe.

For what it's worth, I get the same results (seg faults) whether I
compile openldap with --with-threads or --without-threads

I'd be happy to try out any suggestions.  I don't know much about using
gdb, but here's what I get when I run:

ldapsearch -H ldap://MYSERVERFQDN/ -Y gssapi -b "" -s base -LLL supportedSASLMechanisms

GSSAPI binds (on this server) completely kill slapd.  Have other people
seen this behavior?  Workarounds?
