Hi,
>From the 2.4.40 changelog, I saw 
   "Fixed ldapc++ memory leak in Async connection (ITS#7806)".

The code change is at
openldap-2.4.40/contrib/ldapc++/src/LDAPAsynConnection.cpp


-Del- 46 LPAsysynConnection::~LDAPAsynConnection(){}
+Add+ 46 LDAPAsynConnection::~LDAPAsynConnection(){
+Add+ 47 unbind();
+Add+ 48 delete m_constr;
+Add+ 49 }

But this caused a segV
