If you backup the DB with slapcat and reload it on another server with slapadd, can you still reproduce the fault on the copy?

Unfortunately, yes. It breaks trying to retrieve the same record as before, on the same instruction in back_mdb:

yesterday: [126393.233615] slapd[19244]: segfault at 7f499f38d000 ip 00007f4da0e9b6a1 sp 00007f499f1fa540 error 6 in back_mdb-2.4.so.2.9.2[7f4da0e80000+34000]

A fix is now in git master.
