QLocalSocket issue/difference between *nix & win32

[CmdrMoozy]

So I'm writing an application using qt-4.7.3 that utilizes QLocalSocket/QLocalServer, and I've found some weird behavior when building my application on different OS's.

This code:

int main(int argc, char *argv[])
{
	QLocalSocket s;
 
	// Do some stuff with our socket.
 
	QApplication app(argc, argv);
	MyMainWindow w;
	w.show();
}

int main(int argc, char *argv[])
{
	QLocalSocket s;
	
	// Do some stuff with our socket.
	
	QApplication app(argc, argv);
	MyMainWindow w;
	w.show();
}

Works as expected on Linux, but when the same code is executed on win32 it segfaults when you declare the QLocalSocket. The fix is to declare the QApplication /before/ the QLocalSocket, in which case it works fine on win32.

So basically my question is, why the different behavior, and is it possibly a bug in the QLocalSocket class? (It's also possible that I'm just doing things horribly out of order and I'm causing the issue via that. )
