Description Stephane Delcroix 2013-10-24 08:47:11 UTC
This code compiles, but shouldn't:

		static string DoStuff (string msg)
		{
			string retval;

			switch (msg) {
			case "hello":
				retval = "goodbye";
				return retval;
			case "goodbye":
				return retval;
			case "other":
				retval = "other";
			case "":
				return msg;
			}
			return "";
		}
	}

1/ it returns an uninitianalized variable (might be related to bug#1879)
2/ case fallthrough in the "other" case (already reported as bug#11525)
