if we enable overlay nops & memberof together, then doing a member MODDN operation, slapd will segfault and exit immediately.
Example operation:
dn: uid=test,ou=People,dc=example,dc=dc=com changetype: moddn newrdn: uid=chenln deleteoldrdn: 1 newsuperior: ou=Leave,dc=example,dc=com
The reason is: in servers/slapd/overlays/memberof.c, function memberof_value_modify define mod/values/nvalues in the stack, which will be passed to other overlays, nops will try to free them if no attribute is changed.
