Using Samba4's 'make test', I can hang OpenLDAP's slapd. Samba4 SVN -r 26305

That is, it will not process any further requests, but is waiting in pthread_join(), not stuck somewhere else.

OpenLDAP was built with: `dirname $0`/configure --enable-overlays=yes --enable-modules --enable-dynamic --enable-syncprov=yes

Samba4 was built with: CC="ccache gcc" CFLAGS="-O3" ./configure --enable-developer -C --prefix=/data/samba/samba4/prefix --with-winbindd-socket-dir=/data/samba/samba4/prefix/wb

Samba4 testsuite command line:

OPENLDAP_PATH=/usr/local/libexec:/usr/local/sbin TEST_LDAP=yes make test

This hangs during the 'provision' processing.

Note that this outputs an ldapi:// URL. Using that URL, this test shows it's not just samba that is stuck:

ldapadd -H ldapi://%2Fhome%2Fdata%2Fsamba%2Fsamba4%2Fclean%2Fsource%2Fst%2Fdc%2Fprivate%2Fldap%2Fldapi -f st/dc/private/ldap/samba.example.com.ldif -D cn=Manager,dc=samba,dc=example,dc=com -w localdcpass -x

You should run slapd with -d debugging enabled and (I usually start with -d7) send the info for the last few requests prior to the hang. Also, you should use gdb to attach to the slapd and get a trace of all the threads to see where they've gotten stuck.
