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
