That's way more interesting.  Looks like when debugging librewrite stuff
I'm printing a NULL, which on Linux doesn't harm but might on Solaris. 
I'll recheck all that portion of code; yoru stack trace doesn't indicate
where the accident occurred in back-meta.  Can you step a bit more
backwards?  Moreover, you should be able to complete the test if you
reduce the logs (e.g. with SLAPD_DEBUG=0).

Thanks, Ando.
