Sample wxWidgets application under windows: terminated with status -1

[whyisosad]

I created a wxWidgets project with default settings. Everything is ok when I compiled and started the program, but after closing the appliication window, I got message from CodeBlocks:

Process terminated with status -1 (0 minutes, 1 seconds)

What's problem with it? I'm using wxWidgets-2.8.9, MinGW-5.1.4 and the newest nightly build on XP(with SP2) system.
PS:On my Debian system, it doesn't has this problem.

It's normal in windows. There's no problem.

That's not right !!!

You created a dialog-based program I guessed, there the OnInit-function returns false if it ends, that leads to a program return-value of -1 on windows and 255 on linux  (at least on 64-bit linux).
In the frame-based sample it returns true, what leads to a program return-value of 0.

Thanks for your reply.
Yes, I just meant that "It's normal that the main() function should return a value".
