Hi,
I have the following problem:
On a sycrepl provider I have lots (100+) consumers in refresh and
persist mode.
After upgrading the provider from 2.3.x to 2.4.25 I can crash the server
by a single mod on the root object of one database.
Aug 15 14:18:37 trzs721boot kernel: [544888.798212] slapd[2861]:
segfault at 0 ip 00007fbf89494522 sp 00007fbe8cfa7ca0 error 4 in
slapd[7fbf8942c000+1b6000]
I reproduced this on a test system, even with 2.4.26. The consumer are
ldapsearch clients like this "-E!sync=rp/rid=xxx,csn= * +" on a single
2.4.25 machine. All SLES 11 SP1 64bit.
Here is the gbd output.

I tried to create a core dump, but I could not get it work.
I used this howto. The "top" example works, I get a core file for user
ldap. With slapd it is not.
Why does slapd crash here?
This looks like the same trace as ITS#6892, but that was already patched/fixed
in 2.4.26. Need a bit more info from the crash. E.g.
print *ss
print *ss->s_op
