Without any other clues, this feels like ASLR is messing with us but that's
just a wild guess. I can no longer reproduce the SIGBUS in slapd regardless of
compile options, while ldclt itself keeps dying. If you can find some more
reliable way to reproduce the issue that would help. Perhaps using the client
in test060.

I ran the whole test suite for mdb, and as far as I can see, every test returned OK.

Found a new way to reproduce the SIGBUS using ldapadd on Ubuntu 12.04 firing to openldap on RH 6.3: ldapadd -h 172.17.101.150 -p 389 -D "cn=admin,dc=test" -w test -f test.ldif -- ldif file is the same as the previous ldclt command. Doubt it matters, but the ldif file is 1M adds.

Can you provide your slapd config and this LDIF?

On the RH box:

• compiled openldap with -g -O0 and previously used flags

gdb `find /root/openldap/ -type d -printf '-d %p '` --args /opt/openldap/libexec/slapd -h "ldap:/// ldapi:///" -F /opt/openldap/etc/openldap/slapd.d -g openldap -u openldap -d 0

gdb output: bt -- http://hastebin.com/hefikekaxi.sh bt 10 full -- http://hastebin.com/vudocosuka.sh

Can you also provide the gdb output for print *env

I am begging to doubt that the problem could be on my end as the bt seems to point to schema problems (although, I haven't analyzed it in great detail yet).
