So trying 3.1.x to see if it fixes the 3.0.x error.... :)

Packaged build (so disable-developer) segfaults in rlm_ldap (ldap.c:1431).
Trying to debug that I built a new version which has enable-developer set. That
bombs out in a consistency check in SoH, as below.

Looks like it doesn't like that pair_make_request is called with a NULL value?
But can't imagine that is right as that's normally what happens to create an

About to go home now so thought I'd shoot out a quick e-mail in case someone
else knows the immediate answer without me having to stare at code for a while

(Update on the original issue; I'm going to build against latest talloc and see
if that fixes it - may be just a bug in the older talloc version in Debian
wheezy. That will have to wait until next week now.)
