[Freeswitch-dev] coredump connecting to ldap database from dialplan within lua

[Anthony Minessale]

its hard to tell with no symbols in the ldap lib nor the lua ldap module

if you installed the system lua then built the ldap binding against
that, it's possible its not the same revision.
but you should rebuild both the ldap and the lua binding with debug
symbols (CFLAGS containing -g -ggdb) if you want more info
