Bug#1040382: slapd: debian12 ships with slapd-2.5.13+dfsg-5 which crashes (segfault in dynlist.la).

[Ryan Tandy]

Hello splge,

Can you confirm whether the slapd setup where you encountered this crash 
might have included a global/frontend instance of the dynlist overlay? 
If you still have the logs, can you show a crash report from dmesg?

See additional context quoted below. I would like to know for sure 
whether you and wouldsmina are talking about the same crash.

Thank you,
Ryan
