slapd: memberof.c:1465: memberof_res_modify: Assertion `0' failed.

If you have the core file handy, or if you can quickly reproduce the problem, could you print the value of ml->sml_mod, i.e. from within gdb:

(to see the backtrace) $ bt (where <x> is the number of the frame of function memberof_res_modify) $ f <x> (to see the value) $ print ml->sml_mod
