SDL_CreateWindowFrom() with Qt widget under Mac OS - c++

Question

I am using libSDL2 in a Qt app. The code is working well under Linux and Windows but is failing under Mac OS. Here is the crash output:

That sample code reproduce the crash. Again it is working under Linux and Windows but not under Mac OS.
int main(int argc, char* argv[])
{
QApplication app(argc, argv);
if (SDL_VideoInit(NULL) != 0) {
qCritical("SDL_VideoInit() error: %s", SDL_GetError());
return EXIT_FAILURE;
}
QWidget* qwidget = new QWidget();
SDL_Window* sdlWindow = SDL_CreateWindowFrom((void*) qwidget->winId());
if (sdlWindow == NULL) {
qCritical("SDL_CreateWindowFrom error: %s", SDL_GetError());
return EXIT_FAILURE;
}
return app.exec();
}
