hi,

i've got a problem using syncrepl and back-perl. After the slave connects to the
master, it crashes with an segmentation fault.

I tested it using various 2.3.x and 2.2.x openLDAP-Versions on RHEL 4 and SuSE
10. The provided files are from an OL 2.3.20 on SuSE 10.

The Perl-Module ist a variant of the SampleLDAP.pm that just prints the function
names and the parameters (http://stargate.upb.de/admin/bstobbe/SampleLDAP.pm)

A log file with loglevel -1 can be found at
http://stargate.upb.de/admin/bstobbe/log.txt

(the XXXX blocks are from the perl module)

The core-file can be found at http://stargate.upb.de/admin/bstobbe/core

A backtrace shows the following:
