Comment 1 Zombie Ryushu 2016-04-18 19:18:43 UTC
This only happens whenever I do a net rpc join against my Samba 4 Classic Domain backended by OpenLDAP.
Comment 2 Volker Lendecke 2016-04-19 15:12:25 UTC
Can you run the crashing daemon under valgrind and post the output?

Comment 4 Volker Lendecke 2016-04-20 14:19:33 UTC
Thanks for the valgrind log. It points somewhere else, but I would really appreciate if you could try the patch sent with

https://lists.samba.org/archive/samba-technical/2016-April/113536.html

which fixes a memory corruption with pdb_ldap when creating users. Maybe valgrind just does not catch what is happening there correctly. Please report back if it helps and also if it still crashes. Then it would be great if you could compile Samba without optimization and with CFLAGS=-g so that the valgrind trace and the panic will be more informative.
Comment 5 Zombie Ryushu 2016-04-22 08:34:00 UTC
I added that patch and it still panics.

Comment 6 Volker Lendecke 2016-04-22 11:42:43 UTC

CFLAGS=-g ./configure ...

and re-run under valgrind?
