+Summary: [GMCS] incorrect CS0121 - call to base overriden methods are said ambiguous
+
+gmcs is confused and reports ambiguity for call to an overriden base method
+among further base methods.
+
+--------
+class Foo<T>
+{
+        internal virtual void Hoge (T obj)
+        {
+        }
+}
+
+class Bar<T> : Foo<T>
+{
+        internal override void Hoge (T obj)
+        {
+        }
+}
+
+class Baz : Bar<string>
+{
+        internal override void Hoge (string obj)
+        {
+                base.Hoge (obj);
+        }
+}
+
+Actual Results:
+
+override-override-override.cs(19,8): error CS0121: The call is ambiguous
+between the following methods or properties: `Foo<string>.Hoge(in string)'
+and `Bar<string>.Hoge(in string)'
+override-override-override.cs(3,24):: `Foo<T>.Hoge(T)', name of symbol
+related to previous error
+override-override-override.cs(10,25):: `Bar<T>.Hoge(T)', name of symbol
+related to previous error
+Compilation failed: 1 error(s), 0 warnings
+
+Expected Results:
+
+no CS0121 error.
+
+How often does this happen? 
+
+consistently.
+
+Additional Information:
+
+It still happens when you replace "string" with a generic type argument.
