When i compile and run the below code on linux 64 bit, it core dumps in
ldap_start_tls_s().
#include <ldap.h>
#include <iostream>
using namespace std;
int main()
{
char* hostname = "myhost.mydomain.com" ;
LDAP* l=ldap_init(hostname,389);
int version = LDAP_VERSION3 ;
if( LDAP_SUCCESS != ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, "7"))
{
    cout << "error LDAP_OPT_DEBUG_LEVEL" << endl ;
}
if( LDAP_SUCCESS != ldap_set_option(l, LDAP_OPT_PROTOCOL_VERSION, &version ))
{
    cout << "error LDAP_OPT_PROTOCOL_VERSION\n" ;
}
if( LDAP_SUCCESS != ldap_set_option(l, LDAP_OPT_REFERRALS, LDAP_OPT_OFF))
{
    cout << "error LDAP_OPT_REFERRALS\n" ;
}
if( LDAP_SUCCESS != ldap_set_option( NULL,LDAP_OPT_X_TLS_CTX,NULL ))
{
    cout << "error LDAP_OPT_X_TLS_CTX\n" ;
}
/if( LDAP_SUCCESS != ldap_set_option(
NULL,LDAP_OPT_X_TLS_CACERTDIR,"/myDirOfCert"))
{
    cout << "error LDAP_OPT_X_TLS_CACERTDIR\n" ;
}
int rc ;
if( LDAP_SUCCESS != ( rc = ldap_start_tls_s(l, NULL, NULL)) )
{
    cout << "error ldap_start_tls_s:" << ldap_err2string(rc) << endl ;
}
}
