[Pkg-openldap-devel] Bug#658047: slapd: reproducible segfault during sync-replication on slave

[Sven Hartge]

Package: slapd
Version: 2.4.23-7.2
Severity: normal

Hi OpenLDAP Maintainers,

I experience an easy to reproduce and consistent segfault when I setup a slapd
syncrepl consumer on Squeeze.

This segfault always happens during the replication of the same object, but the
slapd version in Lenny has no problems with same DIT.

My oldstable replicas currently run a self-backported version of
2.4.21-1~dvz50+1, but both 2.4.17-2.1~bpo50+1 and 2.4.11-1+lenny2.1 are also
fine.

2.4.23-7.2 shows the segfault as all versions up to 2.4.28-1.1 do. Even if I
disable all indices and strip my configuration to the bare minimum needed (i.e.
self-defined objectclasses and attributes) I get the segfault.

I am aware the problem my lie in my self-defined objectclasses and attributes,
but then slapd should throw an error and exit instead of replicating 1/3 of the
DIT and then segfault.

I get a very good backtrace, but since this backtrace contains internal
information I am a bit hesitant to attach this backtrace to a public bug-report.

Is there a way to privatly submit this data (backtrace and additional schemas)
so you can have look at the problem?

Grüße,
Sven.
