LibSSH C++ wrapper - Basic remote connection segfaults when leaving scope - c++

Question

I'm new to libssh and trying to connect to a remote machine to run some commands. All of the connections and commands return without error, but then the program segfaults when leaving scope. What am I doing wrong?
Code
#include <string>
#include <iostream>
using namespace std;
#define SSH_NO_CPP_EXCEPTIONS
#include <libssh/libsshpp.hpp>
int main()
{
ssh::Session session;
//Set options
session.setOption(SSH_OPTIONS_HOST, "192.168.200.101");
session.setOption( SSH_OPTIONS_USER, "user" );
//Connect to host
session.connect();
//Authenticate user
session.userauthPassword( "password" );
//Open channel
ssh::Channel channel( session );
channel.openSession();
//Do something
channel.requestExec( "ps_aux" );
//Close channel
channel.sendEof();
channel.close();
//Disconnect
session.disconnect();
return 0;
}

After beating on it awhile, we have a working solution. The first hurdle was recognizing that the remote host must be a "known host". After that, for me, it was necessary to then source the environment before running my executable.
Last, I needed to give it some time to crunch with sleep( 1 ). Enjoy.
#include <iostream>
using namespace std;
#include <libssh/libsshpp.hpp>
int main()
{
int port = 22;
//Can use SSH_LOG_PROTOCOL here for verbose output
int verbosity = SSH_LOG_NOLOG;
ssh::Session session;
try
{
session.setOption( SSH_OPTIONS_LOG_VERBOSITY, &verbosity );
session.setOption( SSH_OPTIONS_PORT, &port );
session.setOption( SSH_OPTIONS_USER, "user" );
session.setOption( SSH_OPTIONS_HOST, "192.168.52.101" );
session.connect();
if( session.isServerKnown() != SSH_SERVER_KNOWN_OK )
{
if( session.writeKnownhost() != SSH_OK )
{
cout << "writeKnownHost failed" << endl;
}
else
{
session.connect();
}
}
if( session.userauthPassword( "password" ) != SSH_AUTH_SUCCESS )
{
cout << "failed auth" << endl;
}
ssh::Channel channel( session );
channel.openSession();
//Source environment if necessary, run executable
channel.requestExec( "source /path/to/set_env.sh; /path/to/executable/..." );
channel.close();
channel.sendEof();
//Unfortunate brute force step, the exec call needed some time
sleep( 1 );
}
catch( ssh::SshException e )
{
std::cout << "Error during connection : ";
std::cout << e.getError() << std::endl;
}
return 0;
}
