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]

today:
[517860.953779] slapd[24871]: segfault at 7fdeb50a0000 ip
00007fe2b63ad6a1 sp 00007fdeb4f0d540 error 6 in
