Re: segfault at 10 ip 00007fbb33028d4e sp 00007ffd8d3bf380 error 4 in libdbus-1.so.3.19.13[7fbb33027000+2e000]

Pardon my sentence in the below email.

I meant, the crash didnt happen while instantiating the host_client.It happened while trying to execute the remote host module.

  try {        syslog(LOG_CRIT, "initlizing host_client");        keyhandler_proxy_c host_client(get_dbusconn(), path.c_str(), name.c_str());        syslog(LOG_CRIT, "host_client is initialized");
        vector<string> vals = {"pwEncrypt","eventd"};
        syslog(LOG_CRIT, "calling key_ctl");        ret = host_client.key_ctl(vals);        syslog(LOG_CRIT, "key_ctl returned");    } catch (DBus::Error & ex) {        syslog(LOG_CRIT, "hostquery - DBus Exception %s\n", ex.what());    }



~~  Thanks, Srinadh

 I see that it is after this line and it happened while executing this line:
        ret = host_client.key_ctl(vals);

Is the crash happening before or after this line? Add some more debugs
to find out, perhaps.
