Ok, thanks for the answer
This is the new backtrace:

I'm getting a segfault while doing any search in openldap. This is my configuration:

slapd starts fine, but when I make any search this is what I'm getting:

and the gdb backtrace shows this:

This trace is useless; since the issue appears to be repeatable, you should retry with slapd built with debugging symbols and unstripped.
Everything works fine in 32bits (Debian 5.0 i386), but it fails with 64bits.
Any idea?
Moreover, you may want to try with HEAD code, where some modifications to deal with 64 bit (long int) key values. Should be unrelated, but just in case...
