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
