+Summary: Assignment of out params is not tracked correctly
+
+mcs complains about the following:
+
+class Y
+{
+    public int bar(out int i)
+    {
+        i = 0;
+        return 0;
+    }
+}
+
+class X
+{
+    public int foo(out int i)
+    {
+        return _y.bar(i);
+    }
+
+    private Y _y;
+}
+
+$ mcs x.cs
+x.cs(14) error CS0165: Use of unassigned parameter `i'
+Compilation failed: 1 error(s), 0 warnings
+
+That's not correct -- in foo, I is set by passing it to bar. The same code
+compiles without error with MS Visual C#.
+
+Cheers,
