OpenLDAP crash on write operation with syncprov overlay enabled

[Alexandre Biancalana]

Hi list,

  I'm migration an OpenLDAP server from Debian linux to FreeBSD 6-STABLE.

  I exported the database from old server with slapcat and impoted at Free
without any problems. But when I enable syncprov overlay and do any write
operation (ie.: ldapmodify) on the base the OpenLDAP crash with signal 11.

 I tested with FreeBSD 6-STABLE (cvsuped sources yesterday), FreeBSD
5-STABLE (cvsuped one month ago) with OpenLDAP 2.3 and 2.4 installed through
ports and packages, on diferent machines PIII SMP, Semprom UP, Centrino UP,
P4 UP. The problem just ocurs when the syncprov overlay is enabled.

Trying to debug this I run slapd through gdb:

I'm very pleased to someone that could help me to figure out where is the
problem....
