Can you ktrace it and see what's happening with the process?  openldap
does a lot of processing for different types of searches (i.e. it will
interpret the search first, and then execute it), so you'll get a
better idea with high tracing of what search is actually getting
executed.  Also turn on all debugging with openldap.

Do you get a core?
