This bug has existed for a long time for me, and I'm finally tired of it. :-( This is 100% repeatable. Start with xemacs -vanilla. Then evaluate (load-library "eudc-export") xemacs crashes at this point. The lisp traceback and C backtrace are appended below. My .eudc-options file contains just: ;; This file was automatically generated by eudc.el (provide 'eudc-options-file) (eudc-set-server "mbb1.ericsson.se" 'ldap t) (setq eudc-server-hotlist '(("mbb1.ericsson.se" . ldap) ("exchange.ericsson.se" . ldap))) Curiously, if I start up xemacs and use the menus to run eudc, everything works as long as I say not to configure my search base. If someone can provide some pointers, I'd really like to squash this bug.
