 Which means that the GUI initialization function has been called.

 Then there is a bug in it. In particular, if it creates a (normal) wxApp
unconditionally, the GUI initialization will be done implicitly. To write
such "dual mode" application you need to provide your own main() and create
either wxApp or wxAppConsole dynamically depending on which one you need.
