Dear Howard,

I did a core dump when the crash occurred at slapd respectively when the ba= ck-ldap crashed. Maybe the output of the gdb can help you find out where the problem is. Please let me know what you need more.

This trace seems to lack debug symbols. Without source line numbers etc. there's nothing we can determine from this trace. Please read the FAQ.

http://www.openldap.org/faq/index.cgi?file=59

The trace shows that you probably have some overlays configured. What overlays? You need to provide your slapd config files if you want any help here.

Volunteers aren't going to go out of their way to help you if you aren't going to provide the needed info.
