If you compile this program with warnings *on* using DMD version 0.121:

//
auto class testClass
	{
	int flag;

	this()
		{
		flag = 50;
		}

	~this()
		{
		}
	};

int main()
	{
	auto testClass t = new testClass;
	return t.flag;
	}

//

DMD gives you the following warning:
//
warning - testmain.d(15): function testmain.main no return at end of function
//

If you change testClass to no longer be auto, or you remove the destructor, DMD does not emit the warning.


Y'know, it'd sure be nice if "-w" meant "generate warnings but continue if there are no *errors*."  Right now it stops dead if it hits a warning, which I think is a bit wonky.
