I'm making some progress on this. That ldap_ld_free() is called from a
pthread_atfork (child) handler installed by nss_ldap.

However, I had a hard time setting breakpoints that where not hit despite
the corresponding function showing up in a later backtrace until I realized
that I had TWO copies of LDAP libraries in memory: One libldap pulled in by
nss_ldap and one libldap_r pulled in by FreeRADIUS' rlm_ldap module.

Question one: Is that alone (i.e. using both libldap and libldap_r) asking
for trouble?

Question two: If not, how do I set a breakpoint on a specific incarnation
of ldap_foobar?
