Accepting a new connection (child signal error)

[Jose David Bravo A <jbravo@xxxxxxxxxxxxxxxxxxxxxx>]

Hello, 

I ran the ssh_server.c with --verbose arg, with libssh 0.10.4 but at soon the SSH server stars and before any incomming connection to the server I'm seeing this error:

I'm wondering if this is normal, I haven't modified the example code. But the example code is working, but I'm not sure if I should ignore this error and why is it happening. 

Thanks,
