After upgrading from openldap-2.4.31 to 2.4.44 I'm getting segfaults anytime I
run 'passwd', attempt to ssh into the box, etc.
this is on raspberry pi (debian wheezy).
Previously running the latest package 2.4.31. Then installed openldap-2.4.44
from source, did slapcat from the old version and slapadd to import it to the
new version. Loads fine and can run simple commands like "id" for ldap users.
But get core dump with password changes, ssh from other boxes, etc.
A%A[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
Core was generated by `/usr/local/openldap/libexec/slapd -f /etc/ldap/slapd.conf
-F /ec/ldap/slapd.d'.
Program terminated with signal 11, Segmentation fault.
#0 0xb6f350a0 in memcpy () from /usr/lib/arm-linux-gnueabihf/libcofi_rpi.so

(ITS#8408) LMDB build warnings on Darwin/Clang for (s)printf
by joj＠mac.com

Version:

URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (90.141.153.214)
Minor code style issue with latest https://github.com/LMDB/lmdb.
There are three (harmless) warnings that clang caught. Essentially it is the
same pattern for all three, usage of ternary operator yielding format strings
with different number of arguments, whereby the last one is ignored for one of
the format variants.
To reproduce, just do "make" on a Mac with Xcode 7.3 installed (thus using clang
as the compiler).
