Did you compile the lib yourself? If yes, you could try to isolate the
issue by adding some debug messages in src/options.c on each line where
-1 is returned in ssh_options_apply():

int ssh_options_apply(ssh_session session) {
 [...]
 --> ssh_set_error(session,SSH_FATAL,"Trying to XY failed"); <---
  return -1;
 [...]
}

This is called by ssh_connect(). And when it returns -1, the message
"Couldn't apply options" is printed.
