Thanks for your fast replies! The 'make install STRIP=""' did the trick.

I ran the server for about a week with no segfaults, then I decided that I couldn't wait for it any longer. So I connected to the server using an LDAP browser, and then after about ten minutes it segfaulted. So to reproduce I need one connection that is reading/updating/creating entries. And one connection that does an occasional read, otherwise the server will keep on running.

The traceback from gdb gives:
